Peavey Roadmaster - Testing

Welp...

That was mostly successful.

The amp works, and sounds come out of it. The clean channel is nice and warm and clear, the reverb works but is a little noisy (not imagining this being an issue with high-gain doom though).

But the lead channel is still fizzy and glitchy and cutty-outy. Which sucks.

Well, from a certain perspective it's quite cool, as it'd be useful for noise stuff, but I imagine it won't do Eric's overall health much good if I keep using it. It's a bit of a mystery as all the relevant valves tested okay and all the big caps are brand new...

I've sent Oli a message to see if he has any ideas.

Eric's Got Some Brand New Caps

Having sent my Peavey Road Master head off to Oli for general diagnosis, I now have him back along with some new capacitors. After establishing that the big filter caps weren't going to ELECTROCUTE ME TO DEATH I began unplugging and de-soldering so I could whip the boards out and replace the caps.



The de-soldering was something of a pain in the arse, not only because a lot of the stuff I de-soldered had no reason not to be some kind of plug connection, but because two of the wires I de-soldered had actually been a plug connection until the mysterious Mr. Previous Owners made something inside the amp explode and then made a bit of a pig's ear of fixing it. There are lovely scorch marks on various bits of the power board.

Anyway, with that done there was some rather more expected de-soldering to get the original caps off and then the new ones were soldered into place.





Eric himself remains in bits as it's quarter to eleven at night so I won't be able to test him anyway. Hopefully I'll be able to to that before Christmas.
