A year on and I'm really happy with my last build. I'm missing building though and would like a new project. I'd like to try an all-DHT SE amp using current manufacture tubes. I don't need more than a quality 2W output; 4W would be nice. I'd also like to set up a PC-based test rig while at it. So, some fun learning ahead.
Having tossed a few thoughts around today, I'm thinking either:
Another option is to directly couple (monkey) a 20A/B to a 2A3, 300B or even EML's AD1 - the voltages are getting into my discomfort zone (circa 600V), but manageable. I've done direct-couple though and would like to do something different... but if my preferred different is not likely to work I will look at other options. I may also consider a 3-stage design, but would probably want a bit more power as compensation for the extra complexity, and cost!
I guess the sky will not fall in if I don't get this right first time; I will just need to factor in my options at the design stage (multiple PS transformer taps, optional top plate/chassis designs etc.) - I wish I had the space and $$$ to breadboard... and my own CNC machine (yes, I have considered it).
Thanks all for reading my out loud thinking. I'm throwing this out there for suggestions - any thoughts on designs that might meet my criteria? What type of builds would you like to see here?
Cheers.
Having tossed a few thoughts around today, I'm thinking either:
- EML 30A transformer-coupled (1:1) to EML Type 50; or
- EML 20A/B transformer-coupled (2:3) to EML Type 50
