And just like my 69A the push-pull driver transformer is OC windings. Ed can do the rewind.
I like these 2 volt filament valve radios. Get them working right and the performance is almost as good as a mains radio. Unfortunately, all the valves in the 65A have OC filaments. So far I've found an ARP12 = VP23 and an AR8 which is similar to the HL23DD. Looking for TP25 and the QPP valve, Mazda QP25.
