Yep! Did just that.
1) He is located in Germany.
2) Tom, N0JMY, make NEW plugin replacements for the octal based
capacitors, is located in Tennessee, and charges less. $59.99 for the
pair. The shipping will definitely be less. In fact I believe shipping
is INCLUDED.
3) I still have a couple of 3TF7s, AND I have a large 10W resistor that
ran for years in a '67 EAC.
I guess if you have the excess $$$, then this individual would be YOUR
source.
