Installing the LED Indicator
The LED on the M2 Power Supply
Board will be the first indicator that we
have power
– I would suggest just
taping the LED
– make sure the metal
leads of the LED are not touching any
other circuitry or chassis
– Note the
Led has not been pushed in all the
way.
Also note that the LED will only work
when inserted the correct way around.
Installing the tubes
Let‟s install our tubes into the board – the supplied 6X5 in
the 8-pin valve base and the ECL82 (or 6BM8) in the 9-pin
base.
Tidying Up
Seeing as we have a number of loose filament and HT
wires coming from the PCB, I would suggest taping the
ends to make sure that they do not short with one another
when we go to test with power!
