I am [Sailor] on both the Dynaco and Transcendent Sound audio boards. Please feel free to go to these sites and check out my posts. Having said that, this amp is one of the cleanest examples of a Dynaco ST70 you will find. The transformers are clean, quiet and they are the highly coveted all cloth lead version. I know of no rust anywhere on the chassis or transformers. The plating on the chassis has it's beautiful mirror finish and the silk screening is in excellent condition. The quad cap has been replaced. For full disclosure, there are some surface scratches on the upper surface but not through the plating. They may be seen when standing directly over the amp. (see picture). The tube compliment includes 2 - 7199 RCA Black Plates, 1- 5AR4 Sylvania Rectifier, and a brand new matched quad set of Electro Harmonix Big Bottle 6CA7's. Arguably, the best sounding of the new production EL34/6CA7's. I am also including the 4-6CA7 Big Bottle tubes that were replaced. At least 2 if not 3 of these tubes still work fine so the new owner shouldn't need power tubes for a long time. Also included is the original and very clean tube cage and a copy of the owner's manual. More pictures can be provided upon request and I'll be happy to answer any questions. I am rating this a very, very conservative 7+. Yes, a little more than the average ST70, but you get what you pay for. I will only sell and ship to the lower 48, I will accept USPO Money Order or PayPal. I will pay the PayPal fees, buyer pays the shipping costs.
