Got open 20s vintage audios keeping your prized set from working?
No problem... Don't discard historical parts or reroute wiring, just bridge the audio with this tiny transformer emulator.... The SST1D
It provides the same voltage step-up and amplifier performance while so tiny it can easily be hidden in many sets. Got two bad audios? No problem, sets are working fine with two of the SST1Ds doing the job.
You will forget they are in there. Just $15 each.
Plus $4.50 shipping for up to 6 units. Payment via PayPal

Additional notes.
Note, My motivation to provide this solution is strictly to preserve historical artifacts. The price only covers my set-up cost from outside vendors and new parts. Labor to assemble, test, package and distribute is my own and essentially free. Anyone is welcome to clone or improve this design but assumes 100% responsibility for their enterprise. As of September 2022, 48 of these boards have been installed with no reported failures to serve as described.
