Setchel-Carlson P-62

[cork]

I checked all the comp's around the yoke, and they are of course OK. This set doesn't have any C's on the yoke winding. But I thought most of the R's and C's tacked on yokes had more to do with flyback activity, ie. trying to keep flyback yoke voltages from breaking down the yoke winding.

I don't know how bright 7JP4s are supposed to be. I have about 6 of these tubes and they are all this dim, even with 7KV on U2. For the above picture the T54 is at max brightness and the Setchel is at minimum, and the whole scene is in a dimly lighted room.

Bad CRT's seems to be my undoing. I just bought another, my third, 10in RCA trying to get a good 10 tube, and this latest one has a terrible lo-emission tube. I have been trying to find a good 21in B and W 110 degree tube for a year, and no luck.
