My DIY 3C is still not quite finished…my 914 is working fine but the last 6
stages (Low Pass) are not completed as Circuit no longer supply high
value inducters…does anybody know where I can get any from..I’m looking
for 1H values
Look into a gyrator circuit to simulate inductors, this is how it is done today. Whether it can simulate high inductance like 1H is the question though. You might have to change the RLC circuit to accomodate lower inductor values for a gyrator circuit.
If your application rules out a gyrator circuit, then try the audiophile component industry. They have all sorts of esoteric stuff but they are expen$ive.
