It doesn't have any tubes in it, but it switches my tube amplifiers and speakers, and I can't find an area to share it...
6x4 speaker switch because I ran out of room on the old 4x2 I built.

At this point, I have a question: How do u safely switch between tube amps, what about output load?
Some of my prototypes
Here are some of my prototype amps over the last few years....
Hope you like them....

Most of my designs (the triode connected ones) don't mind being switched in and out. I wouldn't do this with any old tube amp though. Usually I turn one off before switching to another one, but I have room inside the switch to have dummy load resistors attached when the speakers aren't. They'll be added in when I receive the resistors.
Hi Carlp,
They are Tung-sol 7581A
the "A" designation is important, its the higher wattage, fatter anode version.

Nice.. regarding CK1006 rectifier, did you use capacitor input and limit inrush current with added resistors? the only datasheet I found is from Raytheon, they mention cap input without any details..
