Description: You are bidding on (1) complete Vintage Electron Inc. ATJ (Amplifier Test Jack) upgrade kit for the Dynaco ST70, MKIII, and MKIV tube amplifiers; quality made in USA. This kit replaces the old preamp power sockets/biaset point sockets found on these amps with high quality FR4 boards and gold plated test jack points for setting the bias. Insert your DMM probes into these jacks when setting the bias rather than sticking one probe into the old socket and picking a ground somewhere else on the amp for the other probe. The kit is an aesthetic upgrade as well as a functional upgrade. Kit includes: (2) FR4 fiberglass test jack pc boards, (2) red gold plated test jacks, (2) black gold plated test jacks, (2) single solder lugs, (2) multi-lug terminal strips, wire, new mounting hardware, and complete step by step instructions. This kit therefore includes enough parts to replace the preamp power sockets/biaset point sockets on one ST70, or two MKIII’s, or two MKIV’s (i.e. two jack boards). As should be obvious, this kit therefore eliminates the preamp power sockets so if you want to power a preamp with that socket, you cannot use this kit. First photo shows an assembled jack board installed in a ST70 chassis to show how they look installed (ST70 chassis not included in this auction, for illustration purposes only). Buyer pays shipping. Please note, we are responsible for the board kit only, and once soldered to, all warranties and gurantees are voided except where the quality of the board kit itself is found to be faulty. Vintage Electron Inc. possesses the largest inventory of NOS Dynaco parts available anywhere in the world, having purchased both the remaining warehouse inventory of the old Sound Values/Stereo Cost Cutters Inc. (SV/SCC) operation as well as the remaining inventory of the old Dynaco National Service Center. SV/SCC was the company that purchased nearly 250,000 pounds of Dynaco parts when Dynaco closed it’s doors back in 1979; they also purchased the existing Hafler inventory from the Rockford Fosgate Corporation back in the early 1990‘s. Quantities of some parts (both Dynaco and Hafler) are very limited as can be expected. Vintage Electron Inc. has no affiliation with the old SV/SCC company and we do not provide repair services at this time for any of the Sound Valves brand products. Please visit our store and search under the Dynaco section for additional Dynaco items, search under the Hafler section for Hafler items, and search under the Sound Valves section for Sound Valves items.
