Going from what I find online and checking with Futurlec pricing.
Seems these should work:
- nMOSFET 2N7002 (7c) or 2M7000 (10c)
- nJFET 2N5485 (10c)
The 2N5484 (80c) / 2N5485 (90c) nJFET are a lot more expensive.
What's their main advantage? Datasheet says high speed switching /
RF. Why would that be necessary for audio?
Then power FETs. Goal is to get to +- 300W switching apps (1/2 hp).
Maybe it's simpler to buy an inverter and modify it, or take apart
some PC power supplies.
Price range on Tayda for VA +- 100W is about $0.5 - $2. Parameters of
interest for switching are mostly max voltage and max current. There
are different ratios trading max current for max voltage. Not for
