The HT or the mains fuse may sometimes blow due to ‘flash-over’ inside an output valve.


If this fuse blows, the first step is to replace it with an identical T500mA 20x5mm fuse. The HT or ‘High Tension’ fuse protects the high voltage for the valve supply.

The mains fuse is located in a small tray right next to the IEC mains inlet socket and this can be removed using a small flat blade screwdriver. The value of mains fuse will depend on your country’s mains supply but the values are clearly marked on the rear of all amplifiers near to the mains inlet. Victory exclusively use 20x5mm UL-approved ‘Timed’ or ‘Slow-Blow’ fuses rated at 250V in all amplifiers. Here’s a short video from Victory’s Chief Designer Martin Kidd that might be of interest too If it’s less intense music that you’re playing, turning your guitar down etc. It will, of course, depend on the type of music you’re playing so if you’re perhaps playing music like Slipknot’s you may need, as Jim Root and Mick Thomson do, a noise gate but with a reasonably high threshold setting, which allows them to stop playing without turning their guitar down. Guitars will feedback given the chance: for all the years that I’ve played gigs and having used many different amps over that time, I’ve always made sure that I’ve turned my guitar volume down when not playing and any high gain channel or overdrive off, between songs. If the amp is well behaved with no guitar plugged in then have you tried turning your guitar’s volume control down when you’re not playing it or switching to Gain I? What you’re hearing may be feedback or it may be a microphonic valve in the V1 position.ĭoes this feedback sound happen with the guitar unplugged from the input socket of the amp? Try switching between channels at rehearsal or gig settings without your guitar plugged in and if it still does this, changing V1 (the preamp valve nearest to the input) for a low noise and low microphonic valve will help.
