Brown Electronic Laboratory amplifer 1001 MV

Diameter issue, not length. I have used these cables in the past on my VTL preamp, and a sony amp.  no problem.  Seems unlikely two pins broken inside, certainly cannot see anything when I shine a bright light on the plugs.  I also purchased another set of cables that also do not fit. older cables have no name just says digital high performance cable.  New cables are Aurum.  I was in 'olden time' a bit of a audiophile (magnaplanar speakers, tube amps and pre-amps) but long ago.  too busy to do that now. This is a legendary amp and just trying to get it to work.

pictures speak a thousand words... maybe several thousand

If you have the ability I would just replace the jacks 

Interesting suggestion.  I don;t have the tools, but perhaps can find a shop to do that in my area.  

Thanks

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.
