The Boogie Board

This my first time posting to any kind of board. I've been a fly on the wall for many a forum but have never posted. I'd like to start by saying hi and please forgive me
For any etiquette I might breach.

Now to the problem or maybe not.

Picked up a stiletto ace combo (1x12) the other day. Sounds fantastic (3rd bogie I've owned) but I pulled the head component out and behold a modification. It seems to a copper peice that's from a pre amp tube. Please see picture. Any help would be greatly appreciated with this problem.

I own a stiletto ace head that has the same thing. Its not a mod for sound but it fixed a factory defect on the circuit board that caused both channel masters to work together instead of separately. Apparently there are more than one with this problem.

My ACE has this too..... was a head scratcher.... thanks for clearing it up!
