Nice find! That chassis looks decent. A simple electrostatic deflected set. Take your time in the rebuild and do a section at a time, starting with the power supply electrolytics. Generally you can tell your mica caps by the smaller values, in PF, MMF, uuF or something similar, your paper caps are larger (.01, .001 mf, mfd, uf, and such). Can be a little confusing at first since some of those look like micas. The black striped 'bumble bee' caps are also paper caps and should be replaced. You can take them out and sell them on Ebay $$$ ![Icon_twisted Icon_twisted](https://philcoradio.com/phorum/images/smilies/icon_twisted.gif) I hope you can find a set of knobs, or something that will look correct anyway. Keep us up on the progress.

I'd try replacing the bulb first and if that doesn't do it, then change the 35Z5 and see if the problem goes away.NostalgiaRadioTime — 12:28 AM |
