Hello. I have an Akai GX-912 cassette deck. I got it for what I consider to be a relatively good price, even after I splashed out on a new set of belts, idlers and pinch rollers. I made a tape on it for a friend and, altho with a rough listen it sounded quite good to my ears, I noticed that it was recording slightly slowly when playing the tape on other decks (it sounding slightly faster on these). Also, the left and right channels are imbalanced and I later did some tests of it's recording by playing in some different frequencies and swapping between source and tape and it definitely isn't right in that regard.
I have only just started repairing my own stuff and, altho I am relatively comfortable with the mechanical side of things, I don't yet want to start trying the electronic calibration myself, not yet knowing one end of an oscilloscope from the other.
I would like this deck set up ASAP so that I may start recording with it and so will defer learning to do it all myself further down the line. Therefore, is there anyone in the UK that you might recommend to whom I can send the deck for this to be done or who is within travelling distance from Margate, Kent?
Thanks in advance.
Geoff
