[AMRadio] R-390

[Alan Victor]

It is a wondeful receiver to work on and there are numerous references. On
line there is a R390 modern version of the manual which is over 500 pages.
It is worth downloading and a study. A Video CD of the repair and
maintanence is also available and a worthwhile investment.
