Is my Dynaco Stereo 400 worth repairing for resale?

@buellrider97 : I have an original owner pair of 60 watt mono SS amps from South West Technical Products. Designed by James Bongiorno - full complimentary symmetrical circuit using the then-new PNP output transistors. Before that SS amps were limited to using only NPN output stages. JB went on to design the high-power Tigersaurus amp for SWTP which became the Ampzilla kit. 

@curiousjim : Little known fact is that James Bongiorno joined Rectilinear to work on the model X  speaker. Later he joined Spread Spectrum Technologies.

Interesting you mention the Rectalinear X. I tried to find a pair unsuccessfully in the late 1960s. I found it a fascinating speaker, sort of an augmented full range speaker with a whizzer cone mid range used from 100 Hz to 8kHz, a 10 " acoustic suspension woofer and a simple 2" cone tweeter. Add it used a series crossover  and it was a pretty unique design(even today). 

@curiousjim did you see the seller on the big e auction site selling the upgrade/restore kit for the ST 400?  Has main caps too, two sets left and 9 sold.  

I was wondering if you still listen to the amp at all any more or just storing it and thinning the collection?

Option-B:  People do look for the amp and if you were using it once in a while, and lets say if you were still listening to it once in a while, you could buy the kit, keep it for a future buyer or find someone local to install it as another option.  I liked my old Dynaco amps and when the right person comes along looking for one, decide then. Sometimes I'd like to have mine back to rotate in for fun once in a while. I liked the soft nature sound of that amp. Worked nicely with my electrostatics at the time, and I tried it with several different speakers, never a problem to drive many of them.  

A room mate of mine built an Ampzilla kit in 1975 that I got to live with for a time.  Very fondly remembered driving Cizek 1s.  Was JB also designer of the classic JBL integrated amp model SA660?  I know he did the SAE IIICM and Dyna ST400 around the same time as the Ampzilla.  I was smitten by Rectlinear IIIs when I first heard them, but not by their other models. The X was a very low efficiency largeish bookshelf model, IIRC, and sounded pretty dark to me, more like an AR3 than the III, which had more in the way of transparency to my then-young ears.
