I got an older patient in yesterday. And its far away from home.

Never heard of Oahu but it seems that they even made guitar and lapsteels in the early 1900s.

The schematics i find on the net is little different to this one. This has a pentode as a first stage after summing of all inputs. It has three instr input and one mic input what ever that meens...
There are signs of late work on this and maybe even moddings of adding electrolytes.

Does anybody have schems for this one and/or a good old story perhaps?
