Thanks all, especially Bryon, and Doc for reinforcing the all-important point
Yes, just curious more than anything, but as I already have a good pair of 2a3 amps, I thought it would be nice to build the stereomour as a 45 and just wondered what the folks who have done this thought. Obviously, the amp is a hit whichever way you go, so I'm going to proceed ass planned and build it as a dedicated 45 amp.
Right now the only 45s I have in the house are a superbly minty and clean pair of National Unions from the 40s, but I will also probably try some sophias at some point, or maybe even some solid plate EMLs.
Bryon, I too have upgraded a few parts -- such as Mills resistors for the PS and 45 bias, some shinkos and caddocks in the CCS, and will most likely bypass the 45 cathode resistors with some film caps. Also binding posts and RCAs are upgraded and if I don't build it as a straight power amp, I'll probably use a goldpoint selector and attenuator. The base is coming along nicely, but finishing is stalled due to some cold weather. The top plate is finally on it's way back to me from the plating shop in the northeast, so when all gets here, I can dive in a bit more, though I've promised myself that I have to finish my Crack first. Right now I have a nice SE el84 amp running the Cornwalls, but have no functioning headphone amp, and there is also a very nice WE421A on it's way to me, and I'm sure once it gets here I'll want to use it. My folks gave me a nice AudioGD NFB-2 dac for christmas, and that is what I eventually plan to pair with the Crack.
Anyway, I'm rambling so I'll stop here, but thanks again for the responses.
