Terry- I had forgotten where that console went, and you are right - it is another 37-670. About the only improvement on this tombstone will be speaker reconing and maybe plate/screen voltage changes to compensate for my 128 VAC line.

Gotta check Ron's site to see if there are any ckt. changes on this new 37-670; I'm seeing several factory discrepancies from the original circuit.
