What Tubes for 5150!!!
What Tubes for 5150!!!
right,, add a 12at7 to the position mentioned and get yourself a matched quad of Sovtek 6L6 WXT+ tubes.. they're awesome.
Also, KT66 are the same tube as a 6L6 BUT they are military spec-since military spec are only required to work and not be musical I'd stay far away from them. That is my OPINION & Ymmv. They were originally used in radios and shit like that as power towers-not guitar amps(yes, there were 100 watt military power towers to contact men in the field, and no they did not play Jefferson Aeroplane for the soldiers, lol).
Lastly, I do not believe that you can run 2 different types of power tubes at the same time. Example:what was mentioned was a KT88(which I believe is a military spec 6550). That and a 6L6/KT66 in an unmodified amp will most likely result in some sort of combustion. Avoid like the plague unless you have deep pockets & like your amp in the shop.
peace
Well you could always run it with 2 KT88s or KT66s and 2 6L6s with no mod or you could get it modded to run EL34s. Be sure to replace your pre-amp tunes too, because I'd be willing to bet thats where youre getting all the feedback from.
