Have 4 CU-52 multicouplers with heavy wooden cases. Can anyone tell me
what systems / receivers they were used with, or anything about them?

Can anyone tell me where the CU-52 multicoupler was used? Unit uses plug in

coils and covers approximately 100KHZ - 22 MHZ. Uses 6BA6 tubes and has

both balanced and unbalanced output ( has at least 5 outputs - don't have in
front

of me right now). Came to me in heavy wooden box (should say boxes - have 4

units) and only a few of the plug in coils. The coils fit into a 5 pin
socket and look

easy to duplicate. Any help would be appreciated thanks Ward"

Sounds like your post maybe

Good Luck
