Progress report on RCA 6T74-Good News!
After finnishing polishing of chassis, replacing last two sets of bad controls, tried set.
Still low volume, and, horiz. not working right. I took set apart. Found a mechanical short on plate connedionof terminal strip for hor. osc., and, hh control. Fixed that. Got that B+ back. Found that a replacement carbon resistor on cathode of audio output tube had gone Very high. Replaced that today.... Still haven't tried for video yet, but, put one of my 45 rpm decks on, and, tried for sound. I have very good sound, and, tone control works great. Audio amp fixed...... Either tonight, or, tommorrow, I'll connect my test pt and try for video. Hope my hh control works now...... Bill Cahill
