Teac A-420

My Teac A-420 works perfectly but the meters go peak from the time it is turned on, so I need the Schematic for the Teac A-420 to trace down the problem. the service manual is available but the circuit diagrams are not there. Can anyone help me solve the problem.

Thanks.

I would try cleaning the record-playback switch first. If you don't have any control cleaner, try putting it in record mode several times. This will actuate the switch and may clean it enough to stop the problem.

Thanks for the comment it was helpful. First I found out that the capacitors were bad which made the peak in the vu meters when I switched on the unit but after changing the pinch roller & and inserted a cassette tape it did the same, so I cleaned the record & playback switch as you said now the deck works great.
