Check out the specs below. This CJ preamp sounds great. It is all tube including the phono section.
The balance control has a tiny fuzzy part. But I was told that spray would fix it. Or I can clean it.
When I looked at sprays there were so many that I thought you might have one you prefer.
Being sold as-is due to age. If you want I can box the tubes protected.
Economy freight is included. You will not be disappointed.

The PV2 was a refinement of the PV1. The PV2 offered a similar circuit with the more linear 5751 substituted for the second triode in the phono stage and 12AT7s used as cathode followers for lower output impedance. The PV2 was constructed on a single main pc-board, eliminating the cumbersome wiring harnesses of the PV1, and assuring unit-to-unit consistency in production. The PV2 maintained or improved the parts quality standards established in the PV1.
A muting circuit was added to mute the turn-on and turn-off surges associated with tube preamplifiers.
