Subject: Re: [Milsurplus] Collins plug-in adapter brochure ?

Thanks, Jim. The pub I have is strictly a sales brochure, no schematic and no graphs. But it does show adapters for SP-600, HRO-50/60, and 51J receivers. Date 1954. The one online, I didn't catch
a date on it.

Easily found using Mr. Google, both look identical circuit wise except for filter frequency.  If your example is a bit different then perhaps it would be worth putting up on BAMA but I suspect it is identical to what is below.

Millen 74400 octal plug-in metal chassis on eBay, item # 392289192024, at a pretty reasonable price.

Various mechanical filters are also available on eBay for not much money.
