I am putting a new coil in my amp's Pi-Net.

I am going to use the MFJ259b on the output to find the coil taps (as I did
a few years ago) but I've forgotten some set-up details.

 

For my 3x813's, my notes indicate I used a 2200-ohm load resistor to
simulate the plate load which connects between the tube side of the blocking
cap and chassis ground.

 

My questions are - do I leave the tubes in circuit?  Do I leave the plate
choke in circuit?

 

Thanks,

Steve KK7UV
