[R-390] R-392

[Jacques Fortin]

Hi Adam,
The 1st mixer (V203) or the 1st Xtal oscillator (V401) is not working.

 

Pretty much the same working scheme than in a R-390/URR.

Hey guys,

Doing a little tinkering between classes (18 credits is awful...). I decided
to try out a R-392 that came with a T-195 I bought this summer.
It's nice and clean inside, no obvious defects - but is completely dead
below 8MHz. Any idea where I should start my search when I dig into this?

Thanks for any help or pointers...

Adam
