Parasound HCA-2200 - Should I repair, or sell?

I have a Parasound HCA-2200 that has an intermittent problem with the left channel dropping in/out for a few seconds or more. I have made sure to eliminate any problems with preamp, speakers, wires, loose connections, etc. I tried using the phono jacks and the xlr connectors on the amp and preamp, swapped all things involved... I'm sure it's the left channel of the amp.

If I adjust gain up/down on the preamp when the sound drops out, the channel pops back on. Sometimes, it will come back on by itself if the source volume pops up. Seems unpredictable when it will drop other than maybe due to lack of sensitivity? But definitely comes back when you adjust gain -- doesn't matter which channel of the preamp is being fed into it, doesn't matter about the source.

Bottom line: It's an intermittent problem. Is the amp worth fixing? I do drive it at various times and run a pair of Magnepan MG1.7s with it. 
I have not taken it in for an estimate. There is an authorized repair shop in Nashville. $60+ for "look-see" and $100+ to who knows how much for repair.
For those of you who do bench work, do you think this sounds like it's going to be difficult to diagnose?
Thank you, all! Your help most appreciated.

I've had my local electronics repair place fix a number of units over the years. Their $40 bench fee is applied to whatever cost of repair, which usually isn't much. See if your shop will apply their bench fee to their repair.

You have a well-reviewed amplifier there, so if you like its sound through your Maggies, it's worth repairing, especially as the issue doesn't sound too serious.

if you really like the amp, it seems worth it. Is it the original 2200 or the John Curl Improved 2200mkll ?  that could have big effect on resale as the original got some poor reviews and the Curl model great reviews...

Yes, this seems like a quick and inexpensive fix. Totally worth doing for a decent piece of kit.
