I used your service and I found myself well I need service manual teac v plate 770 and I was able to access and remove the belt that erno routes. thanks I recommend it to all
;
At first I thought there had been a mix up as I required the service manual for the cassette unit and the one supplied was for the CD unit. However when I scrolled further down I realised that both had been scanned together! This enabled me to dismantle and repair the cassette unit as intended and I also have a copy of the manual for both the CD and graphic equaliser units should I ever need them. Thanks very much for a great service.

Excelent service, the manual is complete, very cheap and fast

RDA-7.1 ADJUSTMENT PROCEDURE-1
BIAS & DC Offset Adjustment
1. Connect the assembled channel to the power transformer. 2. Connect the power cord into an AC wall outlet. 3. Turn ON the unit. After about 3 seconds the two green LED's should turn ON. Measure the following voltages and make sure they are within the specifications. C7 (+) : 70 V +/- 3 V C9 (-) : -70 V +/- 3 V L1 : 0 V +/- 0.1 V 4. Connect the DC voltmeter to the test points TP1 (-) and TP2 (+) and adjust the voltage to 4 mV using the R46 BIAS adjustment trimming resistor. 5. Allow the channel to warm up for 30 minutes, adjusting the bias currents every 10 minutes. 6. Measure the output DC voltage and adjust it as close to zero as possible using the R24 trimming resistor.
Main Chassis Check
1. 2. 3. 4. 5. 6. 7. Assemble the chassis / power supply. Connect the power cord into an AC wall outlet. Turn ON the unit. The blue ON LED should come ON. Turn OFF the unit and plug a remote control plug into the Remote IN jack. Turn ON the unit. The Red Standby LED should be ON. Apply 12V to the remote control plug. The unit should turn ON, the blue LED should be ON. Measure the secondary voltages on all power cables going to the channels. Each secondary should read 50 VAC +/- 2 VAC.
