A WE-91B project

I have tried DC heater to 300B and 310A, there is a few changes of noise, so I decided using AC heater finally.


Thanks for all friends in helping me finished this project

Jerry, what a nice WE91 project you have done! What sort of attenuation device are you using with the amp. Do you have the link to purchase the output transformer cores?
