Any amp repair guys on asr that every one trusts?

? That seems awfully strange. Out of curiosity, what was their reasoning behind not wanting to repair it? Was it due to someone else already attempting a repair? In which they feel there might be damage done by said repair, where they aren't willing to take on the repair and be held liable for someone else's poor repair work?
Agreed not a good idea telling them someone may have already attempted a repair.
Is this an authorized Anthem repair dealer or Anthem themselves? Contact Anthem directly, not an authorized repair shop.
Anyways, good luck, I really hope you're able to get it repaired for a reasonable price.

I seen the caps, The only new ones are the brown ones. This in itself should not effect or change performance as they are the same values, the same brand name, but upgraded.
All the other caps are original, with the double sided solder joints. No idea if the main caps are original but the code date is late 2016. So if the amp was made in 2017 they are original, if not, they have been replaced. All the caps on the amplifier boards do, is block DC, as well as keep the circuit stable, as in any other circuit. I would be surprised if any audible difference between channels occurs.
It could be recapped to make everything the same, but i really doubt the new caps currently there, will cause any issue. I Usually recap after 20 years not less then 10

So great news I got the seller to take the mca 30 back. I picked up a mca 50 but in shipping the channel power output plug was damaged. So I need to find a new one of those. So this has the same 15000 uf 80v caps but these are bulged on the tops. I would like to replace them. Is there any upgrade options for these caps that don't get crazy priced. 10-20 per cap range I'm good with.

I have reached out to everyone I can. I place can do it but they want $600 plus easy. Could I downgrade the caps? I found some chemi-con 12000uf 80volt that meet the specs I need. I will only ever use is 3 channels out of the 5. Chemi-con is a higher brand than hec.

Well. Taking into consideration how unpleasant you felt about the different caps in the MCA 30 I wonder how you would feel if you were to purchase an MCA 50 and found out that the seller had replaced the caps in question with lower value ones?
EDIT: Assuming all caps replaced 10 x (15.000-12.000 uF) = 30.000 uF lesser filter capacity..
EDIT #2: Aren't the caps originally 8.200 uF ones?

That's what I have been saying. It seems like caps have been all over the place in these things. Anthem won't tell me what stock size caps were and I do not know how to find out. I don't even know who hec is that made these caps and if there really rated at 15000 uf or fakes. I can get some chemi-con 12,000 uf model now or wait 4 months for 17,000 uf caps later. If it's really 8,200 uf caps stock than 12,000 is still an upgrade.

It sure does look weird with such huge discrepancy. I mean we are talking 150.000 uF capacity vs. 82.000 uF according to which capacitors were used.. Doesn't quite make sense to me. The pictures I found on google shows in either case that 10 capacitors are used.
Strange!
EDIT: This one has the 15.000 uF caps

The one thing I see in all pic's is chemi-con caps were used. But in mine it's hec cd91 caps that I can't find any info on. Also uf the stock caps were 8200 uf 100v wouldn't it be bad to change it to a 80v cap even if it's bigger?

That will depend on the max rail voltage. 80 V is unlikely but there isn't a service manual on hifiengine to check what the rail voltage actually is.

So i found all the amp board caps and they should be here today. I ordered some main rail caps that may or may not blow up. The 15,000 80v caps didn't blow up so i ordered 17,000 uf 80v caps to replace them. I could not find stock 8200uf 100v 35mm caps. Now im wondering what temp i should use on these boards to solder the new parts on. I have 30watt and 60 watt model. I have a de solder gun that's 35 watts to remove the parts.

What's so special about C21 that you would $plurge on a Panny FC??

Splurge wow they were like 60 cents each. This is a anthem mca50 amp. In the home world this will be the highest end amp I have ever owned. I want it to be at its best. I build theaters for other people and install anthem, strake sound, svs , golden ear so I get to dream alot. The newest item in my set is the integra drx 8.4 and if I told the wife how much it was oh boy would she be mad. She was pissed about me building the room and spending over 25k to build one room. Also I would have used all nichicon but they didn't have caps in the specs I needed so I picked panasonic knowing it's a good brand.
