It shouldn't take someone who is properly qualified in repairing this type
of equipment, long to give a valid opinion as to what is wrong with it, so
if you are going to take it to be looked at, pick a place that does do
repairs to AV amps. Pioneer is one of the better makes, and in general,
their equipment is fairly well behaved when it comes to diagnosing and
repairing faults. In my opinion, it would certainly be worth the expense of
getting a proper quote to repair it.

I am going to make a new post asking for local shop recommendations.
Thanks.

What pinball do you have ? I have a
fully restored Williams Cosmic Gunfight from 1982.

Sweet! I have Bally World Cup Soccer '94. A completely different pinball
era than your CG, but plays fast and furious. I have learned a lot about
electronics repair (as well as plastic repair and overall pinball
maintenance) in my 4 years of ownership.
