Sounds like there still is a problem with the startup resistors or their circuit board.
RL2 closes, that's fine but RL1 is supposed to close shortly after the "soft" voltage is present on
the transformer secondary.
If the secondary shows no voltage at all, RL1 will never close and the amplifiers will not get any power.
Maybe a burned PCB track ?

If you already replaced the output stage transistors, there's no reason to replace them again, unless
proved faulty.

The startup resistors have been replaced with 5.6 ohm 5W wirewounds, but the output transistors have not been replaced yet. Now, are you talking about the smaller transformer secondary windings? I didn't check them for proper voltage. I will dig in there. But I do want a quote on those transistors.

Also, the tuner is not remembering my presets...even with the unit powered on! Is there a special memory cap somewhere, or something else?

Thanks for appreciating my avatar. If you're a Muppets fan, there's a whole section of new Muppets videos on YouTube. I highly recommend their "performance" of Bohemian Rhapsody.

No, I'm talking about the +/- 55V secondary voltages.
You can also measure if any mains AC arrives at the (large) transformer primary at all.

The FM presets are stored in a chip on the processor board. The BM8000 should be able
to remember preset stations even if mains was disconnected for a long time (days or more).

Make sure you have everything connected properly and there are no broken solder joints
or PCB tracks, especially at the processor and display boards.
Signals essential to the general functionality of the Beomaster passes through the
display board to- and from the processor board, like f.e. strobe signals for the buttons
on the tonecontrol board (FM store etc.).

Normal is:
Tune in to a station, press "Store" and the "P" will start flashing on the display,
then press the preset button (1-9) you would like to store this station at.

The transistors I will have to look up.

Not a Muppet fan in particular but I do like Stattler, Waldorf, the Swedish Chef
and of course Muppet Lab.

Probing around, here's what I'm getting:

Power resistors: ~115VAC across each

Large transformer: 0V in, 0V out

Small transformer: 115VAC in, 18.5VAC & 5VAC out

I started a new thread about the Delayed Relay circuit.
