My Kraken is feeding back, what should I do?
What you’re hearing may be feedback or it may be a microphonic valve in the V1 position.
My Kraken makes a honking noise on Channel 2 when I stop playing, what should I do?
What fuses do I need for my Victory amp?
Once my Victory amp is preheated (after >1min in preheat with main switch on), can I switch freely between the three positions "Low-Preheat-High"? Or is it necessary/recommendable to turn down to 0 the volume or master and/or to wait a little bit when passing from Low to high or vice versa?
It’s best to wait a few seconds, (only about 5 is needed) if you are going from Low to High or high to Low for the Bias voltage to stabilise or you may get some funny unwanted noises.
Can I switch between single-ended mode V4/V5 and full-output mode while I am in Preheat? Or is it necessary/recommendable to only change this when the amp is turned off completely?
To switch into Single Ended mode you can have the amp fully on, it will not harm anything as all it does is switch one or the other tube off.
I have a quick question re the V40 Duchess - which tubes will break up first, EL34 or 6L6? I would like to know which tubes I can get the most headroom out of.
The 6L6 has a slightly better frequency response than an EL34 so will give a perceived higher clean headroom. There’s not much in it and you wouldn’t notice until the amps is really cranked right up, (you’ll need to be in a big room as those this will be very loud) but in our opinion, we’d recommend the 6L6s.
Just bought a V40 Deluxe. Can I run 5881 output tubes, specifically NOS Tung Sols in the V40 Deluxe?
What make or brand of valves do you recommend for my Victory amplifier?
I own a V45, when switching from the OD to clean channel I get a massive boost in the return of the effects loop briefly. I have asked about and it sound like there are others who have experienced a similar issue with their V30s.
I have a Sheriff 44/Sheriff 22 and would like an option to boost either of the two channels. I've tried an EP booster and a Mini Spark in the loop but without the required outcome ...... i.e. negligible volume increase! Putting them in front just seems to saturate rather than boost!
Returning to your original question; the only way Sheriff users have had some success in achieving a volume boost is to attenuate the signal going into the effects return socket and switching this attenuation off for a volume/gain boost. Something like the Electro Harmonix Signal Pad or a volume pedal may give you the desired results. The effects send level from the Sheriff 44/22 is around -10dBu.
I am inquiring to find out what the year of production on my V50 is. If there is a guide that you all have to assist in reading all Victory serial numbers?
All Victory serial numbers have the month and year as the last digits.
What are the main difference between the V30 Countess and the V40 Duchess?
When using my Victory amplifier there is some hum coming from the speaker; is this normal?
What is the power consumption of my Victory amplifier?
All Victory amps have a V.A. rating screen-printed near to the mains inlet. This is a Voltage x Current rating which is a Wattage measurement. i.e. 160 V.A. equals 160 Watts.
I have a VX Kraken. Is it possible to use the effects loop only to simulate a direct to mixing board set up with a sans amp pedal? I.e. guitar - sans amp - effects loop. Is the effects loop pre power section?
Is there any way I can I preserve the consistency of the power going into the amp from the mains as I get intermittent interference in my location along with voltage fluctuations?
My Victory amp started making some very loud and random crackling noises and I could clearly see a valve was glowing so hot it looked like it was about to blow.
If I buy a Victory V40 Deluxe from the USA, will it still be usable here in the Philippines where we run things at 220volts?
I see people trying to find the centre of the speaker cone when miking up all the time. If victory amps had a nice badge or some type of mark on the speaker grill cloth this would be made easy.
Will the Victory V40 combo sound the same as the V40 head and V112VC cabinet?
Any hopes of a smaller 5-7 watt combo amp coming any time?
I have a Sheriff 44 and I'm curious about the lower power mode. Is the low power mode output only 6w if I crank both channel volume and the master volume? I wonder if it would be safe to connect only one Greenback 25w speaker at 16 ohms and run the amp in low power mode?
Please can you tell me why do you indicate the same bias for EL34 and 6L6GC? (34mV/34mA)
Some bias charts suggest that biasing a valve for 60-70% of the maximum plate dissipation at idle results in the valve anode dissipating much less when running at full power; however, it is rarely the case, when using your amplifier at a gig or rehearsal, that you would play your amplifier as loudly as possible all of the time so biasing for cooler operation and longer life is our approach.
You should also consider that the bias chart you have included in your email is only one of hundreds of similar charts that exist; some will contain similar information as the table below but others will take a different view: Rob Robinette’s chart may be of interest to you.
It’s worth noting too, that if, for example, you were to speak to an engineer at the Marshall factory about biasing EL34s, you may well be told to bias a 50W amplifier with 450V on the anodes of the EL34s at 45mA per valve. Some Fender amplifier user manuals, on the other hand, suggest a quiescent current of 40mA per 6L6 for the best sound, 30mA for extended valve life and good sound but as low as 20mA per valve for the longest valve life.
Biasing valves is not something that is carved in stone, so to speak and the best way to hear the difference is to experiment with bias currents. Higher currents will result in shorter valve life but may be preferable to you, if you like to overdrive the output valves. If you like more headroom for cleaner sounds and to keep preamp overdrive a little tighter, I would recommend lower settings.
Can I fit KT66s in my V30/V40/V40C/V45?VX?
KT66s can be fitted and the same biasing advice applies for these as 6L6s. However, check the height of these before fitting the cage as they do vary and some may be too tall.
I want to be able to use my V30 at home. As it is it's just too loud, could you recommend a good, reliable but affordable attenuator I could use? Have you thought about designing a Victory attenuator or could you come up with a "built in attenuator mod" for my V30?
Are you aware of any companies who make flight cases for the Victory amps?
Yes, we recommend ABS cases as they specialise in custom cases with high quality and reasonable prices. https://www.abscases.co.uk/ Speak to Barry Smith.
My 2x12 Creamback open back cab needs to be run with care as it gets quite bassy, is there anything I can do?
Do Victory amps work for bass guitars or do you sell a separate amp for basses?
V40 Deluxe - can the 6L6s be swapped out for EL34s like on the Duchess?
V130 Super Countess. Is possible to run 4 EL34s in this amp instead of the 6L6s it comes with? Will it have the same switch as the V30 that puts it in the bias range for EL34s?
I recently purchased a Victory Sheriff 44 head. My question is whether it is necessary for the amplifier to be in standby to change bias (fixed-cathode or vice versa) or select high or low power mode?
You do not need to switch to Standby to change the Bias and it also doesn’t matter if High or Low is selected.
My amplifier is buzzing; please listen to the supplied video and let me know what you think.

V4 Series Pedal Preamps - What's Best: Amp Through or Standalone Mode?
If you’re using it with a guitar amp, you’ll get optimum results using ‘Amp Through Mode’ in our opinion because you still have the option of using your own amp exactly as normal.
What if my amp doesn’t have an effects loop?
You can run the V4 Pedal Preamp straight into the front of any amp in ‘Standalone Mode’ though some more extreme settings of EQ on both amp and pedal may be required. To hear the pedal in its most ‘natural’ state, we find higher headroom, cleaner amps work best. Nevertheless, you may very well love it slamming the front of your overdriven amp too. Please try it all because the ‘best’ setting is undeniaby the one you like most!
Can using a separate valve preamp pedal like this damage my amplifier?
No, not at all! Just be sure to make sure of all the usual stuff: speaker is plugged in and you ALWAYS set the masters to ZERO before turning on. There can be some serious volume going here, so please take care.
If I’m running the V4 Series Pedal Preamp into the FX loop return, does that mean I can’t use the front end of my amp as well?
‘Amp Through Mode’ is a four-cable connection method. When the pedal is on, you’re bypassing the front of your amp. When the pedal is turned off your amp’s front end works entirely as normal. The only thing you can’t do in ‘Amp Through Mode’ is hit the front end of your amp with the V4. If you want to do that, please use ‘Standalone Mode’.
Can I still use my amp’s FX loop for other effects if I’m using a Victory V4 Series Pedal Preamp?
Absolutely! Just treat it exactly as you would your own amp’s preamp. You may want to run your delays and reverbs after the V4 Pedal Preamps in your amp’s loop. You may want to run other overdrive pedals and boosts wherever you normally run them: between your guitar and the Pedal Preamp or – less common – in the loop of the amp. Either works just fine.
Will my reverbs and delays in the loop still work with the V4 pedal turned on… and off?
Yep. You’re using your amp exactly as normal with the V4 pedal turned off in ‘Amp Through Mode’. Your reverbs and delays work whether it’s on or off.
What is the current draw: will the V4 Series Pedal Preamps run off my DC Brick?
Probably not – remember there are four valves in there running at proper plate voltage. That requires some serious juice. You need 12V DC and a minimum of 800mA. Each V4 Series Pedal Preamp comes with an included power supply.
Some of the settings of the ‘Bright Switch’ are extremely sharp/dull. Is that normal?
Yes it is, and it depends entirely on your amp. Effects loops vary drastically from amp to amp depending on how the loop and the power stage of the amp are configured. In fact you won’t believe how different they can be… so we included the three-position ‘Bright’ switch on the V4 Series Pedal Preamps exactly for that reason. There will be one setting that is optimum for your amp. There’s no best, no worst – just use the one that sounds and feels best to you, and don’t worry if one of the others sounds broken!
Can I change the valves of my V4 Series Pedal Preamp?
The valves comprise 1 x EC900 triode and 3 x CV4014 pentode. Please replace only with valves of the same type… if you ever need to.
Do the valves in my V4 Series Pedal Preamp need biasing?
They are self biasing so require no bias adjustment.
Can I really not use different valves in my V4 Series Pedal Preamp?
12AX7/ECC83 dual triodes and their equivalents are NOT usable in the V4 Series Pedal Preamps.
Can I use the V4 preamp pedals with a rack/pedal power amp?
Can I use the V4 preamp pedals straight into an audio interface?
Can I use the V4 preamp pedals into a load box like the Torpedo Captor?
I have a multi-effects pedal (usually a Line6 Helix) which I use with four cables method. How can I integrate my V4 preamp into this setup in Amp-Through mode?
- Connect the send of the multi-effects (which goes to the input of your amp) to the input of the V4 Preamp.
Connect the Through output of the V4 Preamp to the input of the amp.
Then connect the amp’s FX Send, which goes to the return of the multi-effects’ return, to the Loop In of the V4 Preamp.
After that connect the Loop Out of the V4 Preamp to the return of the multi-effects.
Finally connect the multi-effects output to the amp’s FX Return.
There is a volume drop when I switch on my V4 Preamp in Amp-Through mode even if I max out the Masters.
First try a buffer or a buffered bypass pedal between the V4 Preamp and the return socket. Usually delays and reverbs have switchable buffered bypass mode which eliminates the loading effect.
Some amps require high send levels, for example some Mesa Boogie amps, and the volume difference comes down to the fact that the V4 Preamp can’t put out such high levels. In this case you will need a boost pedal between the V4 Preamp and the return of the amp which you switch on when you switch the V4 Preamp on.
