RE: Thoughts How much does Plate Structure effect sound on current 300B's?

Posted by Gordon Rankin on July 27, 2020 at 11:18:32:
Willie,

Each company working with 300B's is a bit different. It's not just the plate but also the filament and Grid.

A couple years back Electro Harmonix was having some issues with their 300B. I worked with their engineers over there and they made some changes that made the tube better.

The main reason the different in the VT52 Sylvania and Hytron/WE tube is the filament supply. The Sylvania are 6.3V filament and the Hytron/WE are 7v. It makes a big difference as you can starve the Hyrton/WE if your design uses 6.3V as the reference.

Thanks,
Gordon
