The 'Mule Project'- learning about valve/tube amps on a B25.

[pentode]

The next thing I thought I'd try is replacing the components around the PI valve in case some of the values had drifted.
It's to Ampegs credit that virtually all were very close, a couple were quite a way out but most I think would've been fine as they were.

Measuring around the 7199 again revealed no change in the voltages on the pins...

Not to worry, the old B25 was sounding quite nice as long as I didn't push it too hard. Maybe I'm expecting too much from it.

I have a personal preference for Speakon sockets because of the way they lock. Sooooooooo out with a suitably sized punch and away we go -






Two sockets, one for 8ohms the other for 16ohms - really wish there was a 4ohm tap......







Slightly rushed wiring here but I hope to come back and tidy things up a bit.






That's it for the moment folks.

Thanks for looking by!
