These are very similar to the Futterman H1.
Tubes are 12B4A (same as H1)
The amp uses capacitor coupling. Currently they are big 4uf oil caps. I am planning to replace these along with the electrolytics in the very near future.
They are not quite home made. They were made by MP Engineering of Fairfield Conn. - a small company that was in business for 30 years. I did remove the access panels.

You might have to move some tubes around to get the DC balance - Ralph 11:43:59 06/07/16 (1)
