Wanted: Tech Data for HRO-60

[ashart]

Good day, OMs –

As I continue to work on my new HRO-60, I'm having some trouble understanding the intracacies of bits and pieces of the circuitry, especially in the limiter/detector area.

I'm wondering whether there was ever any technical information available - on the circuitry, performance specifications, etc., other than that in the owner's manual.

I'd be happy to buy any such thing as a service manual, engineering notes "liberated" from National Co., Sam's or Ryder's folders, or the like.

Thanks for your comments es 73.
