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

[pentode]

So, as we're on the subject of sockets, time to put some nice ceramic valve sockets in as the originals were feeling a little loose and I hoped that I could tidy things up a bit.


One of the old output sockets -








So whipped it out (after taking a few pics of the wiring) and cleaned the chassis around it -








The new sockets were slightly larger so rather than grind or file the hole bigger and fill the chassis with metal filings I thought I'd try using a punch even though my engineering background screamed, "Don't be an idiot, you'll screw it up!"
I had to line the punch up very carefully over the existing hole as there was only 1mm / 0.040" all round to remove.....







Taking it carefully left a tidy hole with only a slight burr. Oh and three neat slivers of chassis! -








Repeat with the other socket and fit the new shiny ones in complete with valve retainers - remember, KT88s in the future! -









Next exciting instalment is wiring it all back up again.
