Post Subject: The 13E1Posted by cv on: 3/1/2010

Man would I love to visit the MIT fleamarket... only a few thou miles away alas.

Well, I'm not advocating A2 in any way. The 13E1 will happily run at lower anode voltages but you won't get enough A1 power out, which is a shame cos you'll need a new power supply. But at around 400V, they will bias at around 80V or more, and I think you could probably reuse the rest of the amp - driver, iron, etc...

I'll email you some curves so you can draw some loadlines and figure out the power. There are also some discussions online suggesting that Ultra-linear is the way to go with these for max output, still, I think a combo of more line array and a few more watts from 13E1 may suit you well.
