Brown Electronic Laboratory amplifer 1001 MV


I was given this BEL 1001 amplifier, but when I try to connect the rear cables to my pre-amp what looks like normal RCA cables do not fit into the rear RCA receptacles.  Why? and what to do to make it work?

Tried 2 RCA cables. Pins too large. Are there cables with smaller pins?  Strange.

Sorry but I'm an old tech challenged guy, so I am no help about posting pictures.

You say you were gifted the BEL. Any chance to have a conversation about it with the donor?

no, was given to me by relative of former owner, not longer alive, and relative never used the amp.
