Having acquired an FM-3, plus a spare EMM801 magic-eye tube, I'm interested in a set of boards.

Rebuilding any formaldehyde-phenolic board is difficult, even with a temperature controlled desoldering station.

Do let us know when these are available.

Could anyone perhaps share the electrical characteristic of the sections of the PA-509 transformer used in the FM-3?

Yes, I saw this resource, thank you.
I want to say that the use of UHF blocks on one board is not desirable.
It is also not advisable to use two-sided mounting in devices with a power supply of more than 250 volts.
I made gerber files of PC-7, PC-8, PC-12 PCBs, leaving the correct installation but improving the screening between the conductors. After checking, I'll post these files here.







Hi,
Can you please upload the gerber file of PC-7 using GAA10006 trimmer.
