    I got this deck, however just checked, everything works mechanically and plays perfectly fine, the playback levels are also perfect but the recording is off

    Perfectly adjusted levels to +1DB when monitoring source and recording on brand new tape comes out faint and roughed up lacking low end on both channels. you can turn the volume level all the way max to get to a level you can hear it.

    I do have the service manual but it is not much help on where to get started from.

    Clean the source/monitor switch thoroughly. Re clean the recording head-rub firmly with IPA in the direction of tape travel. After that, it is above my knowledge and troubleshooting skills. (Minimally :)) educated guess is bad components in the BIAS oscillator circuit.

    I have been working on one of these units, I also have a parts unit my issue was a cracked bias oscillator card. In fact both bias oscillator cards h the orig and one in parts unit had a crack in exactly the same place. Fixed card corrected th problem.

    Oscillator card/components on that board (the bias trim pots get very oxidized, pair of 2sc971 transistors might fail, 47uf cap dried out?) definitely points to the symptoms as you describe.
