Took advice from Todd and built the massive version 5 Stonehenge's for the GPA 604-III drivers....

Finish is a very expensive Santos Palesander over 19mm ply...plus a second internal layer of 19mm ply....38mm in total.

Cabs will be finished in Bees Wax polish.

Some internal bracing to secure the middle of the removable back panel, plus minimal sound deadening to be added. Solid billet terminals will be used.

A rewarding and fun project....

Looking forward to getting the drivers in this weekend for testing.....

Amp will be 300B SET....
