Hey all, I have this radio but with no power supply , I have searched and googled to no avail I can't seem to find one , A gent on this forum offered to send me one he had lying around for the cost of shipping , but some reason he must have got busy with other things and never replied to my e-mails , so I am going to try and build my own but the schematics on line really don't give much info as far as supply voltages , would anyone have a actual schematic for the power supply with all the specs?
Thanks

Try the 9P3 or 9P6 schematic under Grigsby-Grunow.

Elton,
I restored a Grigsby-Grunow Majestic 90B with the power supply and TRF on one chassis. Might take a look at that schematic on this site to build one as a separate chassis.

I see them on Ebay from time to time. You could build your own also, at least for the time being.
