Comes with original tubes some of which (GEC KT66) sell for over 250-400 on eBay. There must be around 20 EF 86 mullard original tubes from the 50s Gz32 Westinghouse as well. Two classic monoblocks with newer Hammond transformers. A capacitor has failed and been removed but matching capacitors are still made, aside plugging in and seeing the tubes flow and that all the wiring aside the transformers is absolutely outstanding and original, I really don’t know much more about these units. Priced fairly relative to eBay but open to reasonable offers. All original paint and serial numbers are reasonably close,.. raising money to make a great Christmas experience for my children…
