Binatone01/9014Dead - psu blow upC607 47µ 25v caused it14-09-04

Binatone01/9014Sound dist at high volQ607 2SD400F reg should have 12v at emitter - only 5v at high vol - tr faulty14-09-04

Decca8901Tripping or HT low ( Should be 115v or 109v ) may start up correctly if scan coils unplugged .C803 220uF 16v ( PSU IC supply ) OC.14-09-04
GoldstarKBV-9012E TV/VCR ComboWhite raster with retrace lines, the set switches off after a while. L901 (in series with +180V supply to RGB trs) oc, the +180V winding of Loptx delivers 300V!! (Di&smooth.Cap OK)Replace C820 10uF/160V cap. Note that +180V supply delivers 300V, while +B and all other voltages are normal. Seems to be a weird LOPTx fault, but it was C820 instead.14-09-04
