Recap my ailing Forte 4a?

I had that amp once and other Pass amps too. I would have it rebuilt. The 4a was made from 1988-1991. It was a great sounding amp back then, still has a following and with a rebuild, a better amp to last another 25+ years.

Oh alright, I'll admit it, your Forte 4a is a classic amp. Getting it recapped, even for $850, would still sound better than anything else you could get for under a couple of grand.
$850 seems a bit steep to recap though. You could probably do it yourself for less than half that price. If I recall, you are just replacing the 4 large power supply caps, right?

Firstly, let me say a big "thanks" to all who have responded. 
Secondly, I should add that the 850 is for more than just a recap. It's the price for a Jon Soderberg update that includes IXYS rectifiers and Cardas Binding Posts, plus my estimate for shipping costs both ways from here in Florida.
Admittedly I've yet to hear a class D amp that impresses me beyond the area of improved bass dynamics. Nor have I heard anything for near the current value of the Forte that has me very excited. So I will be going ahead (most likely) with the mod even though I may later decide to part with the amp.

A good idea.  You already have a number of potential buyers who posted on this thread if you do decide to sell down the road!
