Dead as a doornail
#6

Pins on all tubes seem to be good. Plus, I have another one of these Philco's that I restored last year (same exact model) which runs great. I put all the tubes into the 1st restoration and it still works great, so it's not the tubes. With the thing unplugged, I used a continuity meter to see if the on/off control was working - and it does. I used an ohmmeter as well. There are two separate sets of terminal posts, each with 3 terminals. One set, the reading ranges from 186 ohms to about 260 ohms - i think these are the terminals which control the volume. The other set of terminals range from about 300 ohms to 380 ohms - this varies when I mess with the tone control. So it seems like the on/off switch and volume/tone controls are working. Tubes seem to be good. Not sure where else to look. There is a lot of old insulation on these old wires, but no bare wires and all connections seem to be in place. Although I prefer not to, I can swap the on/off/volume/tone control pot from my first restoration and see if this fixes the problem. There are soooo many wires, several capacitors a couple of resistors connected to this control, so I will use this as a last resort, unless someone else comes up with some other stuff to check !!
