Hello all,
I owned years ago the OHR 500 (stupidly sold it) but today I got a OHR 100A in mint condition but without any documentation.

Re: looking for parts polystyrene capacitors
AliExpress has polystyrene capacitors, various values, listed at attractive

Re: Honbay trimmers; I took one for the team
Thanks Dave,
I assume the green paint on the Jameco trimmers is a color code?
On AliExpress I saw ceramic trimmers very similar to the Jameco units at

Re: eBay 330pf mica caps
I received 5 silver mica caps from Aliexpress last week, advertised as "CDE" brand, but who knows? I can't speak to the voltage rating, but they are close enough to 100pF for my use.

Pretty sure these are newly manufactured trimcaps Jim. Man, they are tiny! I got these from Amazon, thanks to your suggestion - and thank you to William K6WHP for the original mention. I don't know if

Re: Precision valued parts
1% capacitors are widely available and not that expensive. Ceramic ones are under a dollar on Mouser. 0.1% ones are a specialty item and are a few bucks each.
1% inductors are another story. I think

Re: AF chain for DC receiver
This version has 3 Sallen-Key stages rather than 2 in the earlier project. Plus there is some filtering in the input stage, but it was not optimized together with the rest of the stages. All this

I don't think I ever posted here before. But I too like to build things. Some from scratch. Some from kits. And some from taking existing kits, such as Heathkit (HW-7, HW-8 on the list) completely

Re: AF chain for DC receiver
Very cool, Mike. Thanks for sharing.
Is the filtering different from the DC receiver AF chain that you posted on

Thanks and 73
