Threshold Stasis 2...Worth a rebuild???

The Stasis II is great sounding reliable amp. By now, all the electrolytic caps, which aren't many, need to be replaced. Most likely, one had gone totally bad on the affected channels driver board and needs to be replaced.

I recapped, my Stasis II a number of years back in an afternoon with BlackGate Standards which are no longer available, but I understand that Jon has some for his rebuild customers. There are some other great caps available such a Nichicon KZ. I also replaced and significantly upgraded the four large aluminum-can power-supply filter-caps with modern version with the same physical size as the old, but of a higher capacity and higher voltage rating. I bought them from Mouser or Newark, I just can't remember exactly where now, but it take a little research.

Bottom line, the Stasis II is worth rebuilding or at least repairing. If you are use to listen to the Stasis II with old caps, you will be totally amazed at how great it will sound once it has been re-capped. It will truly be a new amp like you have never heard. If you send it to Jon, he will do other things beside replacing caps that will take it a notch better including tweaking the bias to make it perfect. Jon knows that amp better that anyone.

Do a search on the Threshold Stasis II at DIYaudio.com. Lots of information on this amp is found there.

I just got my Stasis 2 back from Jon. He was great to deal with. It was well worth it the charge in my opinion. Yes the amp is 30 years old. But with almost everything inside replaced I now have 200W Class A power for under 1500. A great value if you ask me.

Saved yourself a ton of money as well. A new 200W Class A amp today is several thousands of dollars. Jon has done many amps for me and the work is all I could ask for. It is now ready for another 30 years of enjoyment. Don't judge it to early, I have found it takes about 200 hours for all the new parts to break in so to speak. If you like it now, your in for a big treat in a few weeks. I myself let Class A amps on 24/7. Cycyling them on and off and putting the amp in thermal cycles, tend to shorten the life of a Class A amp.

Enjoy it one of the true legendary Class A amps, from the gifted mind of Nelson Pass.

do you still have the amp? I have one and amp looking for a second.

How do I get in touch with Jon Sondenberg Have an old 150 and FET 2. Is the FET 2 worth updating?
