So my Otari MTR12IIC isn't erasing completely. My tech came in said that electronically and mechanically it should be erasing, things are to spech. If we take two passes at it then everything disappears but only erasing once leaves a faint underlying print of the previous recording. It's my mix deck so the current fix is to erase once and then go back and retake the mix but there has to be some fix to this right?
Any ideas what might be wrong?

4There is an erase current adjustment Depending on tape formulation and record level, you may need to increase it beyond "spec." Here's how to adjust it:
Record a series of low frequency pulses at +3vu (ref your normal operating level) -- low notes on an organ or just pulses from an oscillator at 100Hz or lower. You'll need a lot of them so let it go for a couple of minutes.
Rewind this tape and listen to the repro head output while running the machine in erase (silent record). Adjust the erase current until the residual sound disappears.

Thanks Steve. I need to find an extender card to be able to do this procedure. The erase pots are on the pcb and don't have their own pots on the front panel.
Again, thanks.
