PSE Studio V

I heard these amps back in the early 90's driving vandy's. They sounded great and have cool looking wood siding. However, I dont know the first thng about technical issues...

PSE products were designed by Dean Kleinfelter. Great stuff. I do not know what happened to him. Unplug the unit, open the top and make sure the fuses are ok.

This should help you out:
I located Dean Klinefelter in Minnesota and still seems to be involved in his products as he offered troubleshooting help;Phone number is 763-295-1710 for anyone who may need it as well.

Thanks to all! I will try calling and see what happens.

I have had a pair since the early 90's. Used them with Vandersteen 2s and now with 3A Signatures. Still love them. Paired with an Audio Research SP-9 preamp.
One thing to know; they don't like a conventional grounded power cord. So, you have to float the ground, or you'll get a hum. A standard grey 3 to 2 prong adapter will work just fine. I just upgraded to Audioquest NRG-2s and they improved the detail & imaging to a nice degree.

I've known Dean for many years. Great guy. Spoke with him last week. I will be working on a pair of Studio V's soon...

These are getting up in age now and the Muse KZ caps should be replaced on the main board. They are rated at 85 c and the center heat sink generates a hot 63c with the other 2 around 42c when the outside sink is 40c
These are 20 years old now and worth preserving for their excellent sound.
Hifigeek1- contact me about these

Avwerks. How would you like me to contact you?

Been a bit reluctant to call (don't want to bother the man!) and will likely just end up posting these for sale as I can't afford to have them repaired.
