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
