Pete,

FWIW, the MD-7/ARC-5 is rather different than the ATA (or SCR-274-N)
modulators.  They are not in any way interchangable.  The MD-7 plate
modulates the associated transmitter, while the other two screen modulate
the associated transmitter.  The connectors going to the transmitter rack
and to the control box are different between these models, plus there is
an extra connector on the MD-7.

That having been said, the ATA modulator seems to be quite a bit less common
than the MD-7, plus the connectors are much easier to get (at least the PL-
equivalents).

I suppose any interested party would also want to know if the CTT-21626
dynamotor and the CTT-50084 shock mount are included.
