[Heathkit] Regulator for PS-9000 Power Supply

[Mark K3MSB]

Greetings !

I'm trying to fix a PS-9000 power supply for the SS-9000 Transceiver,  and I
think the regulator is shot.

The regulator (Heath Part Number 442-685) is the out of production
UA78GKC.   I cross referenced this to ECG1926, but it seems to be out of
production as well,  although it's still available from a few "out or
production" sources;  I have emails out to these places for prices,  but
nothing's come back yet.   I'm wondering if they don't want to deal with a
customer that want's only one unit.

On the off chance....   anybody have a spare in their parts box they'd care
to sell?

Thanks
