Model 80 Compact alignment
#1

Found this locally for a reasonable price. Things seem to have been mostly untouched, both chassis and cabinet. Keith and I are planning to leave the cabinet un-refinished (except for grill cloth, which is not original).

Keith has redone the bakelite cap blocks, all other caps, and most of the resistors.

Having problems aligning - we've seen both 450 and 460 kHz mentioned as the IF freq, but it refuses to want to hear the signal generator at anything other than about 250 kHz. It does get stations on the very high end of the band, nothing below about 1000 kHz.

Any ideas what we can try? Keith, chime in as I may not have properly described the alignment issues you are having.

Is there a reference somewhere where you can punch in Philco part numbers and see what models those parts were used in?Jim Dutridge — 10:17 AM

Hi OSanders, Look carefully at the band switch. Turn it slowly and "wiggle" it around the desired band. ...MrFixr55 — 12:33 AM
