Well couldn't wait until I finished my other project and pulled the chassis. Well, really dusty. I thought the dial scroll was toasted, all I saw was white. A little light dusting with one of the wife's blush brush (one she gave me) and it came out nice. Same with the rest of the chassis. Did a little cleaning of all and here are the pictures. Will need to find a couple more screws to hold the chassis in. There was only one and one in the bottom of the cabinet. Need to source some rubber grommets to mount the chassis and another chassis bolt for the speaker mounting. Who ever played with it didn't believe in putting back all the hardware.
Here are pictures after cleaning. I really didn't believe the speaker was going to work as pressing a little around the voice coil yielded no movement of the cone. Did a dim bulb and things looked good with the rectifier out. Checked for A/C on the plates and filament, looked good. What the hay, brought it up on my variac and I'll be darn, it plays! Time to put it aside but I'm happy. One more project to finish first. The sound quality sucks and is distorted but the sensitivity isn't bad. Will need some caps changed but waiting on finishing what I have and Chuck to send his nice schematic package.
This at least on the top side looks much nicer than my 112. Couldn't ask for much better. Only 2 tubes appear to have been replaced, all the others seem to match. Engraved Cunningham tubes. I thought they would be marked Philco. Perhaps not then?
