Dave, Is your Philco 17MT80 one with the tuning eye tube? We had one for practice in HS Vo-tech that did. I do remember the cheapo PC-mounted gang pots with blue 1/4" hex shafts. My 17KT50 (19" heavywieght) has them also.

Somebody posted this set was $299 new as it was one of the last 21" color sets (1967)

yep thats the one, with the cheap pots. I remember seeing an add, touting how big the screen was, had some guy holding the set up.

Those PC mounted gang pots on Philco roundies were always a service issue. Not unusual to have to replace them late in their lives as daily watchers back into the early 1990's. The last one I restored had to have every one of them replaced around 4 years ago.

This thread sure helped with my Philco's blackened focus coil- thanks, I have one coming. Could have taken a long time to figure out.
