Atwater Kent Model 35 Troubles

[Winky Dink]

A few days ago I finished the restoration of an adorable little Atwater Kent Model 35.

I chose this model because (1) It fits between my Model 30 and Model 37, (2) I have spare parts to fix almost any electronic deficiency, (3) The shape and the upside-down chassis are somewhat unique, and (4) Most of all, because the TRF is simple enough even for me. Or so I thought.

When I finished the chassis restoration, it looked great:

And it performed well--the best reception and the best audio of any of my radios from that era. And it was loud--had to shorten the antenna to less than 12 inches to have a satisfactory range of volume. Here's a sample of the audio:

But, when I reinstalled it in the cabinet, it didn't work right. Took it out, and it still didn't work right. Here's a before/after audio sample:

I've checked and rechecked all of the components, continuities, capacitance, resistance; retested and juggled the tubes (six '01A's), and in desperation I switched power supplies and speakers. All to no avail.

Here's a couple of schematics which I used. The one labeled "Model 35 Only" is my modification of the Rider/Beitman schematics to show the Model 35 with only one filament rheostat. The Gernsback schematic is original, showing two rheostats.

In addition, Leigh Bassett's modern drawing is at http://www.atwaterkent.info/TechData...wingIndex.html

So, experienced people, do you have any advice for me?

Thanks,
