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?

I have an early version BEL 1001. Never had any issue with a variety of RCA's.

Are the male pins too large? 

Could you describe why a standard RCA will not connect and what you see upon examination?

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?
