[Milsurplus] MRC-19, ARC-21

[Marty R's GI-stuff haunt]

Hamfest guy had a ~10"-long x 2" black-crackle rectangular thing that said

    Osc. - Amp. for MRC-19

    Hallicrafters, '51 contract.

Big bannana plugs & phenolic insulation at connections on either end.

Ring a bell?  Usual MilList places returned little

Now ARC-21. I know it, it's the RCA hf critter-in-a-drum.   Same guy
the sub-mini-ridden RF exciter deck.

Both left behind @ hamfest but think they're retrievable.  About free.
