well ive just bathed the band switch for the i dont know how many times/. i did have a separated contact on the front of the first wafer of the band switch 3 days ago.i thought that might be it (it wasnt). the rivet head had fallen off leaving the contact and wire from pin 2 on t19 hanging in the wind. i thought that was the ball game as removing the band switch was a non starter.luckily the chassis plate behind the knob and front cover was removable and i managed to repair it and change r27 while i was at it its quite miserable to get in there.ive got a factory schematic. ive got a national vp-8177a generator. i was advised to use a 1000pf cap as a probe or at least have it in series from the generator to any point on the radio. so a modulated signal at say c-26 at 110.7mhertz is a reasonable place to start? ive looked with a magnifying glass to inspect my work i cant find anything wrong visually
