Need help?Do you have a question about the TANDBERG TIA 3012A and is the answer not in the manual?
Important notes on unit warm-up, transistor removal, output power measurement, and washers.
Adjust R475 (left) and R476 (right) to 20 mV across R615 (left) and R616 (right).
Adjust R409 (left) and R410 (right) until diodes are off; measure DC voltage on output sockets.
Adjust R123 (left) and R124 (right) to 0V ± 100 mV for MC inputs, and R163/R164 to 0V ± 100 mV for MM inputs.
Adjust R319 (left) and R320 (right) to 0V ± 5mV with volume at 9 o'clock.
