[Mark K3MSB]

Thanks everyone;  I admit to being lazy Ken and I didn't look it up but I

I'm repairing one for a friend and told him he could not use an 8 ohm
headset, so I was looking for a matching transformer or line transformer.
Lots out there to choose from.

I think the Radio Shack 273-1380 should work.
