This set will clik realy when try to turn on. In stby the B+ to HOT is 110V, using a bulb across B+ it is 100V, vith variac it will maintain this 100V with AC from about 70V up to 130V. All switched secondary supplies are low, ei the 16VDC reads about 13V. Replaced opto-isol no change, suspect IC901 STRF6515. Checked all diodes and SM transistors and diodes and ESR all caps in the area. Raw B+ is 169V with 115VAC input. Could someone give my the JVC number for IC901, being JVC don't like to user generic STR Al G Al's TV-Electronics Pembroke ONt.
