OPT connections
It would appear on the secondary side that 6 is the common or - connection and then you select one of the others as the + depending on the desired impedance. It would appear on the primary side that P is the tube plate connection and B is the B+ connection.

Thanks justmikey, missed your post but that’s what I ended up doing.
The ISO are installed and working nicely.
I ran a square wave and FR measurement in ARTA.
Different circuits but comparing to this shootout,

Looks like the ISO are very good to excellent performers?
Can someone explain how to evaluate the HF resonance and overshoot as was done in the shootout?

I was posting it in your two other threads as you wrote this. Once is usually enough.

When I bought them directly from ISO the cost was:
FC-20S output transformers -- $473/pr
LC-10-200DII choke -- $137/ea
$85 FedEx shipping to US from Japan.
I think they had a price increase since then, but at the same time there is now a US distributor so could influence prices and availability.
