Just some things that I want to compare or just try out/build. Some of this stuff I have done in the past but have completely lost touch with the results and just want to try it out.
- Triode driver shoot-out: 5842 vs EC8010 vs 6S45P vs WE437
- Pentode driver shoot-out: D3a vs E810F vs 6688 vs 5847 vs 6Z9P vs 6Z11P vs 6E5P vs 6E6P
- Switch-mode supply for B+/heaters
- Voltage regulator using 6S19P and 6Z1P
- Millett hv regulator
- Silicon Carbide diodes in B+ vs tube rectifier
- SiC vs ultra-fast diodes in DHT filament supply
- LM317 current source vs Coleman regs
- Bias methods for small signal tubes: Fixed (PS and battery) vs Cathode (R and LED) vs Filament
- CCS vs LC vs IT vs RC loads
