George, Thanks for your reply. Do you have an idea of how much a recap would actually cost? I figure that the layout of the chassis will be a bit more labor intensive to remove the boards. I was figuring on $400 to $650 for a full replacement w/o the matrix.
What will I expect to notice with a recap on a Stasis 3?
I recently purchased a completely original Threshold Stasis 3 amplifier. After blowing out the tremendous amounts of dust and visually inspecting, I hooked it up to my system. It still functions and sounds quite good. The bass is sloppy, female vocals are excellent and some mids get a little muddy at moderate volume. It is really pretty easy to listen to with minimal fatigue. Actually, sounds closer to my Conrad Johnson tube amp than the Krell. I expected a little more slam out of the Stasis but certain that some extra capacitance will help remedy that. If I were to recap, what improvements should I expect? Is this amp worthy of a rebuild? Is this amp a happy medium between an ultra analytical Krell and a gooey tube amp?

I’d say 2-3hrs labor at $120 pr/hr, boards are easy to take out. Parts about $150usd. So around $600 odd to do the job just by a good technician, not a amplifier manufacturer or hifi shop, because they will charge like a wounded bull for both labor and parts. Here is the circuit diagram should you need it, only stays up for a while, so save it. https://ibb.co/fdjZvFC Cheers George |
robbieshep OP Pleasure, looks like there are 6 X smaller electrolytic caps on each channel to be replaced, and the 2 big power supply ones, use .47uf plastic by-pass across each of the big ones, or the many little ones I linked to if you go that way, which I think you should for better dynamics and bass tightness performance. I would get 2 of these and give them to your tech, that will be 72000uf per channel not bad. https://www.ebay.com/itm/HITACHI-12000UF63V-6-Capacitor-Welded-Schottky-Rectifier-Filter-Power-Supply/312720173080?hash=item48cf932818:g:sJIAAOSwh8VdQvQR Plenty info here on the board ones, and Nelson chimes in also. https://www.diyaudio.com/forums/pass-labs/297464-threshold-stasis-3-amplifier-capacitor-replacement.html Also here https://www.diyaudio.com/forums/pass-labs/182177-threshold-stasis-bias-thread.html Cheers George |
