Need help identifying

[Ed Richards]

Hi, All;

I have 2 PC boards, fully populated, that I removed from some Heathkits
in the past. If anyone can tell me what they may have come out of, I will
offer them for sale.

!. Has 3ea. IC's and markings CDI, 10/81 QST, RC ACTIVE FILTER.

2. Has 2ea. IC's, 3ea. transistors, 3ea. inductors, 2ea. pots, 1ea. male
and female RCA phono jack and plug and markings 85-1412-3, 121373,
102274. I believe this one was between the LMO and the IF input on a SB
series, maybe a SB-303. I would like to know the function of this one.
Maybe a Q-multiplier?

If anyone wants these, feel free to make me an offer. Thank you.

73,
Ed Richards
