Threshold 400A & CAS-1 amps, SL-10 pre & S1 power supply...?

I have been blessed by the audio gods with these!!

This stuff is insane good!!!

I recently acquired all of these items and would like to know what type of service they may need and who is qualified to work on them in the lower 48. The only issue that I have found so far is that I am only getting the right channel in the phono stage. I have not tried the tuner stage.

So far....ABSOLUTELY IMPRESSED!!!

Thanks in advance for any info!!!

He's joking. Your gear is no good, so send it to him (the Original Pass Labs Disposal Facility).

Amazing gear. Congratulations! Re: qualified techs - Jon Soderberg did some fantastic work for my brother. He specializes in Forte / Threshold gear, but I'm not sure he's still working. He's in CA, so I hope you're close to avoid $$$ shipping of those beasts. If you're handy with an iron, and have a bit of intestinal fortitude, many here could probably recommend how you could give each piece a once over on your own.

re: John - I don't know if he has a web page, but a quick search for "Vintage Amp Repair Citrus Heights CA" should get you the business phone number.

Good luck, and happy listening.
