Home Tube DIY Asylum

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

Isn't it ironic...

I've owned two tube scopes in my life. The crappier one was an old Tek 502 with a plain-jane 12AT7 cathode follower. 500kHz on a good day, drifty, noisy, and not terribly linear. The far better one was an old Tek 545 with a W differential plug-in that used... a cathode follower with a current source load and a voltage bootstrap. Solid. The first scope ended up being stripped for parts, the second sold and probably still being used today.

FWIW.
