USED; Frank Van Alstine upgraded Dynaco Pat-4 preamp in very nice condition------------------------------------------------------The preamp has been hooked up with headphones anda cd player and sound came out of all of the inputsthis unit has three different inputs for turntables one for HIGH cartridgesone for CERAMIC cartridges and one for LOW OUTPUT CARTRIDGES--------------------------------------------------------------------------The actual Van Alstine circuits are a complete redesign of the Dynaco circuits. The original were discrete Bi-polar transistors. The new circuits are F.E.T. OP amp based. ------------------------------------When Van Alstine redoes a PAT-4 preamp he takes all the original boards out and throws them away. He then installs his own designed and built boards and only used the chassis, transformer, input and output terminals switches and tone controls. He installed ALPS stepped volume and balance controls. It is basically a new preamp in the old chassis. FET circuits do sound a lot more like tubes.------------------------------------------------------------------------please look at the pictures of the inside of the preamp to see all the work that Van Alsion did on this unit, the boards, and potentiometers have been replaced. ------------------------------------------------------------------------------------there are some fingerprint marks on the back and the bottom of the unit, but none on the inside. ------------------------------------------------------------old fingerprint marks are normal with Dynaco preamps due to the metal that Dynaco used on their units----------------------------------------------------------------------The unit will be dioxided on all knobs and switches before it is packed and shipped to you.-----------------------------------------------------------------All sales are final with no returns please ask all questions before you buy------------------------EBAY MANAGED PAYMENTS AND SHIPPED WITH FEDEX GROUND PRICE $35
