Hi Guy's
Was looking at Greg's post Philco Aglow and thought it wound be nice to post some pics of my 660L dial. The dial on it is printed backward cause it's below the knobs. To do this all I'd have to do is put a new cord on it and pull the 80 tube out. I've had the set for awhile but haven't done anything to it since I got it up in MA years ago.
Affixed a new cord on it, old one had no prongs on it so couldn't use the old plug. Removed the escutcheon and cleaned it and the dial. Pulled the 80 and put power to it. Was disappointing in that the dial didn't light up very much at all, could just about see the pointer the rest dark. So I thought I'd pull the chassis check the bulbs and see why it was dim.
Now this thing is set up like a chairside in that the chassis is mounted vertically with 3 long 1/4 bolts. If you ever have to take one apart remove the spkr first I didn't. If you don't you can easily smash the dial and shadowmeter. Fortunitly I didn't but it was a close call.
Got it out ok without smashing the dial or fingers I found that the dial and lamps are really filthy, think a good cleaning is in order. This should brighten up the dial.
Was going to work on the 41-300 next but now I've got it somewhat apart and it's a bit of a pain to get back into the cabinet it just moved up to 1st place.
Will start with measuring some resistances of the output trans,field coil, filter choke, driver trans,shadowmeter, and bleeder resistor. The chassis is very similar to the 116B & 116X. Pics to follow...
