Hello, I'm helping a client with a Teac 90-16. The unit has a problem that has developed, it will no longer record or erase. Had previously worked a couple weeks ago.
We've been able to calibrate the repro and sync head outputs with the MRL no problem. But when I've gone to start setting the record bias, the unit will not erase the old material and will not record the input signal.
I'm wondering if it's something to do with the master bias oscillator. I have the physical manual and am trying to track down info from it.
Does anyone have experience working on this machine or solving a similar issue? Any help is appreciated.
