Next case - Odd Philco 42-720 Tropic
#70

And It's Alive...

[Image: http://www.philcoradio.com/images/phorum...e00033.jpg]

I had a NOS GE 5Y3GT tube, so it went into the former 6X5 socket.

I crossed my fingers...plugged it in and turned it on...

In less than a minute, I was listening to my home SSTRAN playing 1950s music. Icon_thumbup

I let it play for a half-hour or so, checking the transformer periodically. By the time I turned the radio off, the transformer was barely lukewarm, and I think a lot of that was due to the heat generated by the 5Y3GT and the two 7B5E audio output tubes, all of which are right behind the transformer.

So once the dial back plate returns and is reattached, this will only need an alignment and then should be good to go. I really won't be able to test SW until then. (Yes, I know I could now, but I don't want the dial cord to come completely unattached. You will note in the photos above that it is being held onto the flywheel with masking tape so it does not come off.)

With these values I think you are OK; the Cmax for this tube is 40uF. Your Vbb could rise a bit, but probably not too mu...morzh — 04:53 PM
