My third Selmer PA 100 rebuild!
Here it is in original shape:
As I always do with these major PA rebuilds, I clean them completely from the old parts:
Clean it from the old dirt:
Point to point boards:
Wiring around the power tube sockets:
Cables for the boards:
And components for the boards:
And get the boards into the amp and try to remember where all cables where supposed to go
And here we have the finished result:
It’s a three channel amp with a tube buffered effects loop, dual switchable master volumes and a solo boost.
Control for each channel: gain, volume, treble, middle, bass. Channel two and three also has a tightness control. Channel two has a three way mid boost switch (low mid/normal/high mid) and channel three has a switchable solo boost that gives a push in the low end, a push in the mids at 600hz and flat out the highs.
Controls for the power amp: Dual master volumes, presence, punch and a three way range switch for the punch.
Here’s a clip of the amp:
Bonus clip of channel 2 and 3 before the amp was finished:
