Very similar
to the Mk1, the chassis is now mounted at the bottom of the case,
upright;
as-opposed to upside-down plus, the addition of coloured smartie knobs.
Most of the
coloured smartie knob centres were missing on this one. I replaced them
all……of
course!
A new pair of
JJ EL34’s [E34L’s] always do the trick when output
tubes are pretty well worn!
Finished and
on a final test-gear check-up.
These non-PCB
type of boards are about a “half-way-point” between
a real PCB and (or) the turret/tag
board way of wiring. However, with an overkill of soldering/repairs
etc; too
much solder can cause Stalagmites (or should that be Stalactites?). The
whole
board was of course all cleaned-up and re-soldered accordingly.
Side view of
same board removed.
Things all
back in-place.
As some
previous technician had at some point not replaced the mounting screw
at the end
of the board, it had of course “been flapping around in the
wind”! This eventually
caused it to crack right across the underside print, as can be seen
here!
This, without hesitation, was of course sorted and secured correctly!
Whoops! A
leaking cap! Yes, this got replaced too!
