Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

No this is not an comersial product

I am not sure about the grid stoppers. But due to the size of them I hardly think they are ww-resistors.
Still I have ha hugh stock of HOLCO-resistors, even though not carbon composition I think they are suitable for this application.

No, this is not an commercial Product. I bought it from a friend whom designed it severa years ago.
Initally my idea was to use some of the fine parts in it for my own design. But after using it for some weeks, I decided it was better to make new chassis for this one. And in the process, also make some improvents (if possible).

Whats worry me most is my fairly hi Zout frpm my sources, driving a fairly low Zin at this amp. Ideas such as replacing the 25K volyme for a 100K dito came to my mind. And also try the E280F as a pentode for decreasing the miller cap.
Anny ideas around that?
