For Sale:
IC: Stax 'KGSS-A' electrostatic amplifier (EU voltage)

Will Ship To: Anywhere

This is an interest check for my KGSS-A, which is a SRM-727A modified with both the Spritzer mod, and, especially, the same output stage as KGSSHV. I carefully followed Kevin Gilmore's instruction in order to do so, and the way it is now, it's a KGSS with current source modification (which was how the 727A improved over the 717), and using more modern/better transistors than what was used in the KGSS, the 2sc4686 (used with the KGSSHV itself).
It's much purer sounding, airier and smoother than the 727A (before and after the Spritzer feedback modification alone), and has better bass control.
I have also replaced one of the two Pro-bias outputs with a normal bias out, using a Stax original nb connector, and Kevin's instructions to give it normal bias voltage.

Condition of the amplifier is great. It operates at 220V to 240V.
Reason of selling is that I am going to build a diy SRM-T2, and I need to raise as many funds possible.

I'm looking for 1500 Euro, in Europe. Worldwide buyers will have to pay for a shipment premium. Payment by bank transfer, or buyer pays Paypal fees.

Thanks,
Tony

Hi Tony

 

Did you successfully sell this kgss-A? I am looking for sth better than my srm-007 for my Omega I. Interested in how you modded the 727 output to that of kgsshv. Could you explain a bit?

Hey Dreksler, I'll drop you a PM as to some alternatives (even for your srm-007t)
