I bought some socket savers to make these out of. Damn these things are expensive!
I will make 2 versions.
One will be a drop in and use the 6.3V heater circuit in the Aune.
3rd one will be a 6SN7 adapter that is a direct plug and play. This one will have a small circuit in it to bias the 6SN7 correctly. No external power needed.
So what about the converter plug I posted that is 6SN7 to 12AU7..is that missing something ?
I like drop ins !!! LOL so the AUNE uses the same heater as the 12AU7 (6.3V)?
