Hello Powerking!

I just acquired one of these awesome units myself, (Serial 5941) and I'm now hoping it arrives mostly intact. I've found the manual and schematic over on 'bama but it doesn't include a parts list or values. Could you point me to a link that has these, or share what yours has? I'm going to try to get the parts ordered so they arrive before or shortly after the unit itself and I'm not stuck in the same boat you were at the time of your post.

Can someone also possibly confirm that "type IV" was later changed to "1V" (both are 4 pin low drop rectifiers.) in case I have to source some working bottles? (I have 3 compatible eye-tubes, but the rectifier has me scratching my head a bit here.)

I think the banana jacks are just a common retrofit that owners made over the years. I think we've all owned at least one piece of test equip with a lead snapped off in the pin-jack.


Thanks in advance!

If it was mine, I'd change the jacks to the banana type.
The 1-V tube is available at ESRC for $5.00. Not all that common of a tube!
It has a 300ma heater, where the 6X5 tube, has a 600ma heater
I have an older Detrola radio, that originally had a 1-V rectifier. The socket was changed to use a 84/6Z4.
