[NLRS] Instrumentation Amp Help

[Donn Baker - WA2VOI/0]

HI Zack.
That's a shame, although not unexpected, as it was a real steal at $40.  Its still a good deal at $75, though.  The 
active part, the HELA-10B requires some other parts most notably the input and output transformers.  Its not a simple 
MMIC like the ERA or MAR series parts.

Oh, well.  At least I was smart enough (read, lucky) to get a couple when I could.
