Someone had been an electronics tech for the Merchant Marine in Norfolk and was going to open a retail and repair shop when they passed away. Their inventory was sold at auction by wonderful and honest people who however dont know a resistor from a Mexican jumping bean. This is not a Dynaco kit, it is a clone of one. The Dynaco ST-70 was made in Taiwan ROC in the 90s and retailed over a grand. These copies made by Shenzen Valve Audio Lab currently retail about a fourth of that. still no small potatoes. I have no choice but to sell it AS IS because it is not practical for me to attempt to count the screws and capacitors but I dont think anything is missing. I expect the former owner was planning to assemble it but I dont know what happened to the original outer box, when people pass away they rarely organize the workshop first. Maybe the heirs piled odd junk in it. Whatever happened to it, the box was not part of the kit. I do believe everything is there but I cant swear to it, that said you can see by the sections in the styrofoam being filled everything in that bit should be there, and looks like the remainder as well. Interested buyers and this means you, if familiar with the model are encouraged to message with a description and/or photo from the net of any component they consider crucial and wish to verify. Shipping by the most advantageous method either USPS or UPS, depends on where you live. May be picked up in person in Virginia Beach for no surcharge. It is rather heavy, as you might expect but the two services are in half of a price war so shipping might not be so bad as it used to be.

Only one stereo board left:Stereo Dyna YOD board with 2 sockets for 6GH8s, and you get 2 NOS 6GH8s made by Ei in Yugoslavia with Telefunken tooling. I think these drove EL34 / 6CA7 / 6550 / KT88 which have similar bias voltages. Someone in NY has sold 14 pairs of these same 6GH8s for more than we are charging with the board

For sale are these new tube amp PCB printed circuit boards, $9.99 each, take a plug in socket for two 6GH8s.so im guessing they are stereo and drive a quad of EL34 / 6CA7 / 6550 / KT88s. (these all have similar bias voltages and pinouts). Price is $9.99 per boardthey are marked Stereo Dyna YOD
