Paramount Transformer Upgrade II

[Brillo]

A plate choke with 70mA+ and 30H-40H (or more)?  Do I have that right? 

 

[Paul Birkeland]

Yes, the 300B design center is 70mA, and you want as much inductance as you can fit. 

 

[Paul Joppa]

The stock choke is about 24 henries, for what it's worth.

There is always the BAC 80 (80ma) which is huge. From Magnequest. This has wire leads.
Also I ran across this the other day
