[Johnson] BIAS plug for Thunderbolt amp

[Steve Bookout]

Hello all,

I'm new to the group, but not new to ham radio, or boat anchors. Have a 
bunch of Johnson stuff, and just found this group.

Question for anyone.

I am looking for the small 4 pin plug on the back of the Thunderbolt 
that deals with the bias.

Does anyone have one that is excess to their needs?   Or, know what's 
it's called in the 'real world'?  Or, where I can purchase one?

I don't believe this reflector allows pics, or I would post one.

Any help would be appreciated.
