quote:[By runeight] ericj, here's a thought for you. Batman and mains_hum tell me that the Stoopid sounds as good or better than the Cavalli-Jones amplifier. The Bender OTL (which, I actually modified to work correctly in the article) is identical to the CJ except for two things: 1) it uses 6N1Ps and 2) it needs a 350V B+. This means that it is likely to sound about the same as a CJ.I am wondering if it might make more sense build a Stoopid first. It will cost less than $50 and it won't have the extremely high voltages. If it sounds good, well then maybe you don't have to take the next step. Or, even if you do, you'll have a nice portable amp to listen to while you're building the next one.
Well, here's the thing. 1: I already have a very nice potted transformer with a 285v 95ma secondary and 6.3v 2.25a secondary. 2: I already have nearly all of the high voltage caps required for the 6n1p-otl. All I'm short, really, are a handfull of resistors and the .47uf 400v caps. And two 6n1p's, as there is currently only one in the closet. This is not the result of an intentional collection of parts - i just turn out to have them already. 3: 6n1p-EV are ubiquitous and much cheaper than more sought-after 6922.

Also, if you decide to build an all tube amp, might I suggest that the 6922 CJ would be an easier build.
Can you explain why? |
