Amp repair...What to expect.

Just got my amp back from repair shop. I know there's a burn in period for new electronics, but would new caps, transistors, etc. result in a lack of detail in the sound? What are the typical changes to the sonics after service?

It's a Sunfire 300 and had every thing replaced except power caps; they did not need replacement. (Sunfire authorized service shop).

Many thanks.

Yea maybe 2...3 years indeed or what?
Rule of thumb is if it sounds bad out of the box, the burn-in won't fix that.

I believe that. So many on the forum say "I'll keep burning it in until it sounds good."

If Bill worked on your amp rest assured it will sing better than new with 50 hours or,so of burn in.

Grannyring, dont know Bill. I checked for recommended Sunfire repair and bob & rita's is closed and Roland has a 8 to 10 week wait. I wont give the name of the shop, but they are in Pittsburgh and only service Carver and Sunfire.

As I understand they've done the job on dead channel and as a matter of fact decided to replace the same elements in the live channel too. As a living studio and stage techie, I would probably be able to take a look at repair project done if you can post pictures of an open box. Output transistors in particular close-up.
