Does anyone know where one would purchase the SP-117 Inductor for this circuit?

It is a discontinued Triode part - keep an eye out on eBay. Or, sub another similarly spec'ed inductor.

Scroll through I believe there's suggestions for alternatives. I found that Triad SP-117 inductor once, the cost was outrageous though.

Thanks Gents! If i can find the specs, perhaps we can have a few made for everybody!

900mH

I don't use the inductor and my step filters work just fine...

There was someone a while back who did some SPICE simulations which revealed pretty much no difference between using an inductor or using a 100k resistor...

This is the inductor I'm using, dirt cheap made in china. triad RC-5. 915uH

[Structo]

Now is it a 900mH or 900µH?

[marshamps]

I believe it's gotta be .9h I saw the Spice sims that were posted and agree not any diference from a 50 ohm resistor or wire, but as long as wer are trying to be accurate..

Using china parts looks I was wong . It's been 32 years since I have used inductors or choke coils. Panasonic makes a choke coil 8200uH or 10,000uH. .820H or 1.0H

Hi , this can work?

Most likely, but that is really expensive for what it is (especially if you are not in the EU)

[dreric]

I'm confused. Is the inductor

900uH

or

900mH

It doesn't seem to say on the schematic and I can't find a spec sheet for SP-117.

1H = 1,000,000 uH
