It runs RA70's, RA80's, and RA90's. 4 at a time.

Yep, you got it!

The DESQA is skunk box version of the DELQA.

It's a perfectly standard connector. The components near the connector
are, in this case, probably nothing fancier than some electrolytics
for bypassing. Is this reasonable? My TK70's are currently in running
