6505 mods

Post by Jackstraw89 »

So I recently came into possession of a 6505 combo. It’s not working. So a tech friend and I are gonna have to crack it open anyway. While we’re in there I was thinking we could mod the clean channel to something a bit more interesting. I’ve heard Soldano has a great clean circuit, as does Dumble. But does anyone else have any thoughts?

Fix it as is before you do any mods.

These amps typically blow out output tubes which then in turn open up the screen resistors and blow the V+ fuse.

Be sure to look at the tube socket solder connections to that output tube board while you have it out and are replacing those 470 ohm screen resistors.
