Thanks to both of you, Fred R. and Poston Drake for you needed help! On your problem ,Fred , my crackling was caused by a leaking C302A cap. inside the IF can following the7R7 tube [27MMF] replaced it ,noise is gone ! Poston, your correct ,I'm measuring neg. voltage ,plus lead on pin #4 of the 7F8 and the Neg. on pin #1 W/a 100,000 ohm isolating resistor on the neg voltage ! I checked R409 tonight .it's ok , I'll check C418 later I"M NOT CUSTOM TO SEE MICA CAPACITORS GOING BAD !! The Philco service info claims -2v, you still feel -o.8v is close enough ??? What is the best way to CLEAN the waffer swt.'s and the locktal tube sockets , I've tried to clean them , you both may be correct and the problem could be their !! Thanks Lee Petrie
