RC-12 Tube Manual

All the tubes I am using in my Hi-Fi System were being manufactured by the time the RC-12 was published.
But I also keep an RC30 copy!

Jensen Ultraflex redux
A few updates to the Jensen Ultraflex
 |
| Revised crossover + EQ/HF boost |
The fixed resistor attenuator was inspired by the Jensen Duette crossover + recent knowledge gained in boosting frequencies above 7khz using an EQ network in my Altec 2-way XO experiments. Try it on your Heathkit SS1 or Eico HFS1 which AFAIK, used only a 2uf beeswax paper cap + L-pad.
 |
| Damping removed paper in oil caps for crossover and EQ |
Happy Listening!
