Galaxy 44v diode?

They have those "controls and headers" connector issues too, dirt gets into the knob and switch, making it sound scratchy - best to just give it a shot of a simple tuner cleaner.

If you remember the Mongoose or even the Detta-Force early vintage models? Uses headers - similar setup - you switched around headers and the Echo worked - but the knobs went back to the board, not the main PCB - which generates it's own issues. So even a cleanup - burnish of the side panel to right-angle bracket to board mounting flange may be needed. If you'll note in your echo photo - you have "press inserts" even for the clamshells - so the Oxides of March are upon you...Happens every season...

I actually liked the echo in this board - but the age is usually what kills the fun of even using it - when it's old - it is old - and sounds like it - which, sadly a little effort in clean up is not what too many have the patience for.

Well I did change the 50/50 control pot because no amount of cleaner would clear it up and the shaft play showed it'd seen more youthful days. The connctor plugs all checked ok too. I agree with you Andy, I too like the echo of those older boards over the ones of today. Now after I replaced the caps it did clean up but not as much as I would have liked it to do. I'm starting to think I spent so much time on it that I became a little critical but the other side of me just didn't like that hiss it made me at a higher echo level. I just don't recall other older rigs sounding that way. Anyway I really appreciate you fellas and your input as you always do so well.
