I also have a plan to build TSE. Collecting parts for my build especially transformer. In George's site he mentioned for the top quality Xformer

Quality Output Transformers
Electra Print (Electra-Print.com High-Fidelity Audio Tranformers and Tube Amplifers) had two transformers that are useful in this amp, BE5KB (5.3K ohm impedance for 45 type tubes) and TM3KB (3.4K ohm impedance for 2A3's and 300b's). They were about $145 each, though Jack's catalog has changed over the years. Jack can also wind you a custom transformer to your specifications.

Do you or anyone have any experience if the Hammond 370EX you're using has higher sonic quality than Electra Print BE5KB that he mentioned ?

Thanks,
Tom
