6N2P-EV Preamp tubes.

[karpathion]

I've been seeing these things go for nothing on ebay, for a long time now. The listing always says its a12ax7 alternative. Other people are starting to use them now, and I wouldn't want to miss out on these prices.

I looked up the spec sheet, and the are pretty close. Would only take a few minutes to change a couple values and make them work.

It's hard to pass on the price, and just a few minutes of work. I'm going to try one in my little Valve Jr first. If it sounds pretty good, the Windsor/2203 is getting the other 3.

$8.50 shipped for a quad.

You can just rewire a 9 pin socket and they work.
