I have received the Akai CR 80 D and I and my hifi guru
this afternoon we have tested and cleaned it .
Unfortunately one channel is dead and the reason is ( probabily )
an AA 072 ic bad .
It's no longer available but it's possible to replace it with
a small discrete circuit .

Except this failure everything is perfect !
No problem : it was a calculated risk and next week I will build this circuit .
AA 072 bad is a common failure on Akai RTR and 8 track decks of '70s .
