Brown Electronic Laboratory amplifer 1001 MV

The cables you're having issues with you've used before I'm assuming.

I'm curious to know what are the cables that will not fit.

The problem is the pins have too much diameter not a length issue?

You are right that it's a great solid state amp. If it's a MK V then you are extremely lucky.

I think @oddiofyl is on to something. Find a good tech to change the jacks and verify the unit is otherwise hunky-dory. 

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?

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?

There are some schematics on D.I.Y. forum that would be useful for most techs.

The BEL is not a familiar design to most.

I would want the whole amp rightfully looked over. It's just too strange with those jacks.

Tom at Brooks Berdan retired. I don't believe they offer amp repairs anymore.
