Amp repair cost — is this right?

I recently sent my Musical Fidelity a308cr power amp off to be recapped. This amp is somewhere around 16-18 years old and one of the power caps failed. I contacted Musical Fidelity and sent it to a repair shop they recommended. Today I received an estimate to replace 18 caps, 8 of which are large power caps, resolder the boards, and re-bias the transistors. Basically a full overhaul. The quote I received, including return shipping (prob around $100) Is over $1,300 which possibly exceeds the value of the amp. That doesn’t include the $115 it cost me to ship it out. Having never had an overhaul done on a power amp like this, I’m wondering if anyone with experience can tell me if this sounds right. I guess I was expecting something more like $600-$800 but I don’t know why since I really don’t have a frame of reference. Perhaps it was the assumption it might be 4 hours labor (say $400) plus max $200 for caps. Is $1,300+ on track? Either way I’m going to be out the shipping cost plus a $160 fee paid for the estimate.
Music Technology does terrific work and they are fair when it comes to pricing.  That is not to say that the shop that did the original appraisal is overpriced or otherwise not a wise choice.  At this juncture, that shop is the only one that really knows the scope of the work involved, so any other appraisal offered here is closer to a guess than anything else.

If you go with Music Technology, the one sort of downside is that they are pretty busy and may not be the quickest alternative out there.  They are good, but, that is no secret, which is why they are busy.
It would seem fair to me....I sent out my working Ayre amp to Ayre...  was this and that (don’t remember the parts)....1250.00
@grannyring @atmasphere @teo_audio - thank you for the direct experiential feedback and thanks to everyone else for what turned out to be a FAR more lively discussion than I ever imagined when I posed the question!

At this point my plan is to contact the original repair shop and ask a few more detailed questions about what they are doing. All I got on the phone was "replace all the caps, re-bias the amp, re-solder the board, $1,340." If it sounds somewhat close to reasonable I will proceed. Otherwise I think just based on the great interaction I had with Music Technology, I'd rather get it back and send it to them even if it's not going to save me money given what I've already sunk so far.

Hindsight being 20/20 I should have asked for repair shop recommendations first, but I did some forum searching and found a couple of (old) recommendations for the shop where it is now, then Musical Fidelity themselves recommended them too, so I went with it. I've only ever had one other amp repaired (not for caps) and unfortunately the gentleman who did it (great work and very reasonable) was a one man operation and passed away several years ago.
@stringreen ,
I have sent a number of pieces of equipment to Ayre.-Some for repair, others for upgrade.
In every case, the price they quoted for repair was very, very reasonable.
One of the caps in my MX-R’s blew. I sent both monoblocks to be checked, and Ayre provided a very low price to have the offending amp repaired as well as checking the other.
The only bad part was shipping them back to CO, as far as cost, but they included shipping with the repair, so I was very happy.  And, I bought all my equipment second hand, so they could have soaked me.
So, if they charged you $1250, it must have been something serious or a very expensive part.
