Sony | PST22 | LOW LEVEL NOISE | Turntable, develops a low level static-like noise which isinduced into the audio ckt. The cartridge used also affects the level ofthe noise. An ortofon LM-10 produces about twice the amplitude of aSony VL-7. Grounding the motor shaft to ckt. ground el | ||
Sony | XR70 | IMPROVING AMS RESPONSE | AMS would not operate for tapes with less than 4 to 6 secondsof silence. Problem appears most often when rewinding close to thebeginning of the tape. | ||
Sony | TFM7720W | DEFECTIVE OSCILLATOR | No FM. All voltages looked good. All transistor wereconducting. Osc. was not working. | ||
Sony | PSX45 | REVOLUTION NOISE | This unit produced a HEARTBEAT sound (one per revolution ofthe platter) which increased in intensity as the tonearm moved toward thecenter. This noise was being magnetically induced in the cartridgewindings. Scoping the motor drives revealed spikes on | ||
Sony | ICR4800 | NO AM RECEPTION | No AM. | ||
Sony | ICF2001 | COULD NOT RECEIVE AM STATIONS | Pins 2, 11, 12 and 13 of IC201 were inconsistently outputtingdata. Latch IC205 was not able to switch antennas to receive AM stations. |
