Hehehe best way i could describe it...
Basicly, as described in my previous thread, im trying to restore the family 9090 that has finaly come home but suffered some in-law hands inside.. Protection issue is resolved, onto the next issue...
Turns out, the radio and pre-sections were dead due to a failure in tr1-3 on the power board.. I used NTE289 on tr 1 and 3. I used NTE152 on tr2..
Upon power up, i was greeted with music however, the sound would cut in and out. I hooked a meter to pin15 and noticed the power level was dropping off a few volts every second in rhythm (like a turn signal on a car)
Seems to be only in this power area as nothing else (lights, amp,protection relay) is affected... Power supplied from D01 is steady.
Are my new transistors suspect???
