what value of resistor should be used from B+ (22.5 Volts)to plate of detector to bypass the primary? The transformer is a Jefferson 3-1, detector tube I assume was a 01A.

Hi John

Values aren't critical. I used 22K but any value + or - 50% of this will work. Here is something I wrote on the subject years ago.
