OK, So, a little update, I started compiling a list of capacitors I need to redo this set and while I was in the process of seperating the chassis from the picture tube I accidentally damaged the original speaker, which just so happens to be a permanant Magnet type speaker similar to what you would find in any modern clock radio, so it looks like I'm gonna have to cannibalize an old clock radio for a speaker for the TV, what's weird though about the original speaker in this TV is that it was being powered by only one wire, the side that would normally be the negative lead had the wire coming off of the voice coil and into the connection terminal block and grounded the negative voicecoil wire lead to the speaker chassis. Has anyone ever seen this done before? I haven't and I find it rather unusual and I don't think its going to be possible to replicate that in a modern speaker because usually the voicecoil wire is snipped off right at the soldering lug for the voicecoil wire on the terminal block for the speaker and so it wouldn't be possible to ground the voicecoil wire to the speaker chassis unless I were to take a wire and jumper it off of the voicecoil wire connection and to the speaker chassis (or in this case the rivet that holds the speaker connection terminal block to the speaker chassis.)
Anyways It seems that the high voltage section of the TV (the back side of the metal portion of the chassis that the High Voltage Rectifier tube, Damper Tube and the Rectifier tubes are attached at) has about 10 wax paper capacitors of which about half of them look a little toasty like they had gotten a little too hot somehow, and showed signs of the wax coating on the outside of the capacitors getting charred or burned somehow, and even some of the resistors near those toasty looking capacitors looked a little toasty as well (but they were only 1/2 watt resistors so the resistors couldn't of gotten too hot themselves unless they shorted.) Any ideas as to how or why these paper capacitors got toasty looking like they did?
