hi Matt -

thanks for the reply. They do sound (and look) like powerful units... big
and meaty build quality, typical of vintage RCA stuff. (Have some of their
845s too). That would be quite the audio amp (400-500w!) but I'd not know
where to start. Nor for VTTC's using them either.. is there a good recipe
somewhere on the web for using these? If anyone wants one or two I'd let em
go for $100/ea. or whatever is reasonable.

thanks,
-Ed
