The Amp Garage

yes.....lots of trouble after about a year in use in the tonestack. Don't use them any more and I swap them out when amps come back in for service.

I've had this very issue recently. It was a leaky low voltage cap near the PI valve. Remove the cap and clean the board thoroughly.

I have found that placing an 82K resistor directly across the volume pot brings the clean channel back to a usable sweep. Does not affect the reverb drive of the drive to the overdrive valve.

I use the James Tone stack after the O/D section. Gives great versatility as you describe with flat response as needed. I use high value pots so that I don't load the anode so much ...and the loss is less also.

I see you are in Italy. This is one of my soldering stations (also have Oki/Metcal and Weller). [http://www.ersa-shop.com/ersa-icon-nano-elektronisch-geregelte-l%C3%B6tstation-standby-antistatisch-p-364.html] I find this station is very good. Have it 4 years and use it 9 hours/day. Very reliable and...

Come to Ireland Cliff. Especially the West Coast. Lots of good eating, drinking and music. Would be a pleasure to show you around.

Matamp still very much in business and can supply replacement transformers.

I use cage nuts (m6 rack nuts) mounted at the bottom of the chassis and 80mm countersunk Allen head bolts fitted with dress washers Looks good and very robust

I hang it from the top because I want the option of using them in a combo or a head.

Russ. This is a strange sort of hybrid. It's got a JMP 50 watt power stage a Fender clean channel with reduced value bypass caps and a Dumble OD section with post OD 'James' tone stack. It also has a Fet driven parallel effects loop with return level on the front panel. Sounds great

Yes. That's an oil finish.

Love the way that this one turned out.

+1. CE is mandatory and additional earth bond, insulation, leakage and HiPot testing must be completed during build.

Here's my version with an ECC82 as the driver and recovery. Works very well.

Here's the second from last prototype being demoed by a good friend.
(I had to make several changes to the graphics on the rear panel)
