Hi Everyone -
My brother's Forte 4 lost the left channel after a power surge. I didn't have much for diagnostics while travelling, so I did what any responsible little brother would do... I gave it a VERY brief once over ... found a dud negative rail fuse... didn't see anything else suspect ... replaced the fuse ... and powered it up. The left channel came back up / warmed up.
I didn't have proper tools nor schematics while I was on vacation to do an in-depth review of the amp. I saw that it warmed up, and that the offset was <20mV. I sent him on his way. So, when he got it home, he hooked it up. The volume was lower on that channel, and then the replacement fuse blew after a few minutes.
So, someone with the proper tools and the schematics / service manual will need to give it a look. I had John Soderberg go through it many years ago and do all the updates etc. I can definitely send it back out to John if necessary.
However, I sent it to John before I ever became active in DIY. I'd have my brother send it to me, but I don't have schematics or a service manual. Also, if any of the parts need replacement, I may not have easy access to replacements.
Plus, it's is pride and joy (as it should be). So, I'd prefer to have someone that knows these amps go through it.
tl;dr - Does anyone know someone they'd vouch for in the Western NC area (near Asheville) or within a few hours drive that could repair the amp? If not, I'll have him send it off to John.
Note - My brother found https://ncstereoman.com/info/category/home/page/3/
Heck if any of you are willing to give it a looksee, I'd be more than grateful.
Thanks in advance.
