P/HP-850 that looks and works great. This is a class A preamp that I used with a parasound amp. All indicators work and there is no static in the controls. It has been reliable and a joy to use during my time with it. Please feel free to ask any questions on it.

Very good condition. Works very well and sounds excellent. It is pretty sensitive to the dirty power in my house and can pick up the 60Hz buzz as a result. I recommend having a good power conditioner.

Very good condition. Seems to have a slight buzz when tone controls are bypassed, but works very well and otherwise sounds excellent.
