Here is an example with a lucky end result: ... C5SET.html

Ha! I remember that circuit, makes me laugh every time I read it and I even had an old console with the same setup same amplifier and all.... It blew up after a couple minutes of use LOL :D So always use an isolation transformer, but I suppose you could double fuse it and have a 50-100 watt light bulb as a limiter. :)

To get the right voltage you could just use a TIP50 regulator but all of the tube circuits I have tried on lower voltages such as 50V have worked, they just have much less gain.
