Thats OK. I have a great sense of humor too. Anytime I can help I will.
I have been here 34 years and have a lot of parts that I will probably
eat. Including about 1,000 tubes.

Thanks Max...Nope...Il is too far away. I think we have a couple left in
Canada.
Hope you know me well enough to appreciate my sense of humour. I do
appreciate the offer, but she sort of wanted me to get it repaired
before it was brought in.
Long story.

Ed,
About a month ago, I was working on the same model. I put (3) LA7832
chips in it. Having no more, and seeing a tip in Winstips, I put it a
LA7833. Worked fine. Try it if you have one. Ken Smith

Bob;
You are absolutely correct. All were bad. But alas...still flat lined. I
presume I have a bad new Vertical O/P IC. Although it calls for a 7832 I
replaced it with a 7830, which I think should be OK. But seems to me I
had a
bad batch of LA7830, because I had a ?? on the bag. So I'll order
the LA7832
and give it a fighting chance.
Thanks.

See the following:
JVC Vertical Failure
You most likely have all or most of the following components defective
in
that unit (these are the usual bad components with vertical IC failure
in these JVCs) so you better check or replace them all: IC421 (part#
LA7832)
D422 (part# MTZJ75-T2) (75 volt zener)
D541 (part# RGP10J-5025-T3)
R541 (1.8 ohm, 2 watt)
C424 (100mfd/35v)
C425 (470mfd/35v)
