Transconductance measured an underwhelming-but-well-balanced 40/42 where minimum (65%) is 50/50 and 100% is 77/77

They were made by Ken-Rad although one is branded "Crosley

They are not suitable for guitar amp application as they are somewhat microphonic

I am listening as I write and this album sounds pretty good
