Even if I find that that it was a bad tube, I need to go back and re-restore it. It was only half done, in my opinion. Lots of rotten insulation wires are left in the chassis. In a few months, I will get around to buying a small workbench a work light as well as an adjustable arm lamp. Trying to work with a flash light, even just to look into the chassis, stinks. The chassis on this radio is so cram packed that it's hard to make heads or tails out of things. It might be due to poor restoration or maybe it's just the nature of the beast.

Well, this cap you showed cannot possibly, due to the way it is constructed, be 1000pF (0.001).

No, that cannot be the 47.
The 47 is a regular backelite block cap. Look at the chassis picture, it is shown there. Rig...morzh — 01:45 PM |
