Hi Everyone, I got a bunch of parts leftover from a failed 300B project from 10 years ago. I'm looking for assistance to incorporate this parts into a new DIY 300B build. I really like the Skunkie Design Budget 300B schematic. I would like to learn how to size all the components based on the Power and Output transformers that I have (ClassicTone 40-18069, Edcor CXSE25-5k-8ohm).
The Secondary Output of the ClassicTone is as follows:
380 V (RD/YW)
330 V (RD/WH)
0 (RD)
15 V (VI)
0 V (VI)
15 V (OR)
0 V (OR)
60 (GY)
0 V (GY)
6.3 V (GN)
0 V (GN)
I also have Neurochrome's 300B PSU R2.0 power supply and two each of his Universal Filament Regulator R3.3 5v and 6.3v and their 21st Century Maida Regulator (adjustable up to 495v) for B+ supply. Not sure if I want to use all of that. Would definitely need testing before use.
Thanks in Advance,
Bobert
It's looking great!!!
UPDATE:
Power supply components are shorted out. I had to have some PCBs manufactured for the 5v regulators. Many thanks to PCBWay for the speedy fab and delivery. I'm almost finished with the chassis design (see image below). Next... start sourcing parts.
