Radiotron Designer's Handbook
Most of my knowledge in Audio DIY have been gleaned from the Radiotron 3rd Edition. The 4th Edition is just over the top of my head, but looks better sitting on my bookshelf ;)

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!
