I would like to add a (tube-based) phono stage to my SP-P. Integrated, that is, on the same chassis. Because I have no engineering skills whatsoever, I'm not sure how possible or practical this is. I know a lot of you like to toss ideas like this around, so if it's build-able, I will buy the parts and heat up the soldering station. I have quite a few 6922 and 6DJ8's to play with. The loading would be for a 47k MM-type cartridge.
