Electronics Repair in Denver

I have a friend with a 35 year old onkyo A-5 integrated amp. I'm encouraging her to have it recapped. It's starting to sound fuzzy. Any recommendations for a service place in Denver. Thanks.
Try Listen Up. They have a few stores in your area, and do repairs on site.
50 miles north of Denver in Loveland try Don Barr at The Sound Doctor. He will have it for a while but if it can be fixed he can do it.
