The Fault A nice Tone King Imperial Mk1 ( http://www.toneking.com )arrived with a strange fault. When you turned up the reverb control there was this horrible buzzing sound which increased as you tried to increase the wetness of the reverb. Faults like this are usually the reverb cables, plug and sockets not being earned correctly or even a faulty reverb pan. Not this one! Read on ….. Background on the Tone King Imperial Amp Mk1 and […]
A two rock Gainmaster 35 arrived for a service. It is manufactured by the Premier Builders Guild LLC. A fancy name! The amps are made in California and are around £2000.. They are built on a printed circuit style board which looks very like tagboard . See in the picture below. This amp is extremely well made and is a relatively simple straightforward design having two pre-amp valves, one phase splitter driving the two 6L6GC
A Laney VH100R amp head came in for a service. While “nothing” was wrong with it, the owner decided just to have its health checked out. This is a really high gain amp with 6 ECC83/12AX7 pre-amp valves driving 4x EL34B to give a 100 watts out.

I received an Orange Tiny Terror for repair. It had lost its voice ! I had never worked one of these amps so an exciting new experience. It is built into a nice metal case and is a very conventional circuit using two ECC83’s and two EL84’s in the output.

A very sick Mesa Boogie Caliber DC 10 amp arrived for me to have a look at. Our first Mesa Boogie Amp repair. This one had one dead channel and my 22 watt Fender Deluxe was as loud as this amp. The Mesa Boogie is a 100 watt amp so something was up. It also sounded naff. Mesa’s have a reputation of being complex and difficult to repair. I had never seen inside one but
Here is a customer’s feedback on replacing the EL84’s with Sovtek EL84’s. I have only removed the customer name I promised you an update on the Sovtek EL84 valves and how they handled in my Bugera V22. Well I have been using them for about three months now and I am absolutely delighted with the changes they brought to the Bugera Infinium V22’s tone and even ‘feel’.

We recently repaired a Bugera V55 Infinium amp. We added a Bugera V55 Infinium video to our video channel . There has been a lot of chatter on especially North American forums about these amps so we thought we would show the amp repair with an amp that was blowing fuses. We then did a quick review on its build and features and then finished off with a couple of suggestions to improve the amp.
