Default Re: Akai 1721 L Recording Problem

I'm not familiar with this machine but do you have a circuit diagram for it?

If so then I would be looking for how the recording bias level is set.

Failing that, if you record the same content on the same tape a second time does the dullness happen in the same physical place on the tape? Perhaps not from your earlier use of the machine??

I assume that it is not a bad contact on the recording switch?
