Hi All

Again sorry I must repost this as well

I went looking for my post in freelists but could not find my most
recent posts??

Anyway

THis set turns on (relay click) then turns itself off almost
immediately.
HB+ =131.6 v
IC 3442  10V in and 5V out
+15VBS ok too!
Chirp of SMPS when plugged into 120V as it should.
Jumper out relay --still no High voltage

If you disconnect the Horiz. Yolk wires the set stays on a little longer
and brief
sniff of audio heard.

H. Out transister tests OK

ideas?

TIA
