Laney Klipp100 amplifier after modification. The master volume pot was a mod already made. It now holds a switch for channel selection, a 6,3mm jack for remote channel switching and indicating leds for each channel.

This is what’s to be the V2 of the PS-1A clone. It’s got a new main circuit board with onboard in/output jacks.

Here’s the circuit installed in the chassie.

Here’s a Zachry D250 solid state amplifier. It stopped working producing only a 100Hz noise. Look at them blue filter caps, seems a bit swollen.
Here’s a picture from the bottom of the caps.
Those caps are out of date. Had a hard time finding 15000uF 63V caps with a diameter of 35mm. Finaly found and ordered F&T :s with the right values but a diameter of 40mm. I should be able to fit hem.

The plan is to fit it in this one.

A word of warning. Never install your power cord like this!
Found it when replacing a bad power cord in an old amp. Had the new cord installed properly with the ground wire directly to the chassie ground.
The ZOOM pedal in a new colour and hardware mounted.
channel mod was made on the amp it saved a half 12AX7 preamp valve. Decided to use it as gain recovery stage and add an effects loop to the amp.
