Qualified service technicians disappearing! Recommendations wanted

I have used theservicedepartment.com in Bridgeport CT for recapping Krell amps and preamps.  Better quality parts than going to Krell directly.  They list warranty service for Mac.  

Why do you think you need a Mcintosh certified repair shop? Any qualified storer shop can fix Mac gear, it's not specialized, or overly complicated. 1yr is ridiculous, just find a good local shop, or something kind of local have them take a look. 

Have you just opened it up, removed, cleaned then replaced all the fuses? Could always be something stupid like that. 

Firstly, so glad I reached out to this forum...great input and thank you all.  I am reaching out to several of the resources suggested.  I do have a decent amplifier that is filling in adequately while I get this addressed.  I will report back once it's all fixed.  As to the suggestion I take it apart myself, I confess I'm not confident to do more damage than good so while it very well could be "something stupid like that", in most scenarios I'd be the stupid one for trying.  Thanks again all!!!

Technicians with tube expertise are declining, and it’s mostly due to poor compensation related to warranties servicing from manufacturers. I spoke to a guy in New York City who is retiring and there’s no one there to take his place so he’s closing his business.

. McIntosh pays its authorized dealers terribly and obviously causes warranty work to be low priority in their shop.

I bought new components from McIntosh a while back and they needed to be returned and fixed and the piece of gear would’ve taken four months to get repaired. Fortunately my dealer was awesome and replaced the component.

McIntosh is clearly falling short in this area and this was ongoing before they were recently acquired. Fortunately they sell very reliable products but all of a sudden we got resale issues of used products which is a factor in buying this companies products. So they need to get there servicing act together and turn repairs around more quickly. This is a management problem and they need to do better.
