This one I acquired about Sep 2014, Kirk has the cabinet. Yep he is still having it. No rush, Kirk. I have just started.

First things first.
Tube test.

78 tube shorted all across electrodes.
41 tube shorted on one of them.
.....And the  guy said it was working and even offered to turn it on.
Well....for 20 bucks I do not hold it against him.
6A7 is weak in pentode section (typical).
6Z4 rectifier is on the high of "Replace" which tells me it will work just fine.

Looking for tubes I found none....until I realized I have a junk 39-7 chassis that was staring at me all that time. I bought it in Kutztown from some guy who was selling junk out of his van. For 5 bucks. I needed the speaker. Which worked BTW. And it has junky cabinet with perfectly fine dial and glass, and a bent-shaft volume regulator. 
So I started testing tubes from there and they, despite the dirt, all tested fine, some like new. So I have the 78 and 41, and my 6A7 test 850 in pentode (typical I see is 300 to 500) section, and my 6Z4 ain't week no more......

Well....I am taking it slow. I literally drag myself into the workshop by my hair. Well....it's getting better.
