[R-390] R-390A problems

[DAVID MEDLEY]

I posted this message last week and received no responses nor did I see i=
t on the list.
I have had trouble with my ISP lately so I hope it gets through this time=
.


I have here a very nice SW R-390A which I got in a swap deal. When I say =
nice it is as clean as can be and the mechanism is as smooth as silk. The=
 flip side is it doesn't work, at all.
I have found two problems unfamiliar to me as I have never struck them in=
 an R-390.
1. The AC power cord has been replaced by a three wire with the green wir=
e connected to the chassis. When I connect it to the outlet the protector=
 red button on the outlet releases cutting off the power. If I disconnect=
 the ground from the chassis this problem goes away. Bad line filter?
2. The cosmos PTO dies when tuned above about 2.3MHz. Changed tubes sever=
al times but that is not the problem.

I solid stated the power supply and that works fine. The 150v checks out =
OK.
3. The audio module is dead. Don't expect to have much trouble with this =
and I do have a spare around here someplace.
I may have some kind of depot dog on my hands?
