I have a 1970 Monarch 10EE that I've been doing a bunch of electrical fixes too. After acquiring several parts, those that I ended up not using or needing any more are available for someone rebuilding the original electronics.
I have 4 of the large tubes. All four appear to be working fine. The machine has run with them in the machine.
I have 5 of the smaller tubes. 1 of them is New Old Stock in a box. Again, the others seem ok.
I have two of the black control boxes. They exhibit different sorts of issues. The diodes are all good and I have some New Old Stock diodes available. One of the control boxes was working. The other is questionable. I'm guessing it needs some capacitors changed out.
I have two filament transformers for the tube circuits. Both of them work fine.
Any interest, please ping me.
Thanks,
