Our biomed department had a bunch of stuff that was taken out of service and was going to be recycled, so as usual I went through it and found a cool looking box with a handle on top that will make a nice little mini-amp.
I did not expect what I found inside though - a real live tube! It was made in 2002 and I was shocked to see a tube still in use. It's a 6146B, and the unit is a blood coagulator thingy where they use high voltage/frequency signal to burn the tissues to stop bleeding.
The transformer is stamped "700v" but actual readings are 800v R/R and 7.0v on the green pair. It's not very big which makes me think the current supply isn't going to be real high, but it should work fine for an SE project. We have one more of these still in use but when it comes out of service they're going to send it to me.

If you figure 7.0 should be 6.3, then 800 should be 720. If you put the right load on it, voltages should come in closer to spec. I expect maybe 700 was for 117V? Assuming line is now 121v, 121/117 is another 3% differential that would get 720 down to 700.

RF cautery, oh boy! I've seen it in use, one of modern medicine's little miracles. You might make a nice little SE amp outa that. Or power up an electric fence. Or something..
