Myles- Called Groove Tubes (no decent local deaters) and ordered some 6V6-S tubes, in a #2 or #3, a 12AX7 Matched Phase Inverter, a 12AY7 for preamp, and just so I have one, and ECC 83(?). Will let you know how it goes. Thanks for the suggestions. I ordered from Rick- he mentioned the 6V6-S as being new. Thanks, Seth [/qb] Seth, Lots of wrong directions here.... The 7025 is the brightest of any of the 12AX7s. The "red" 6V6's are the hottest .... BUT will break up the LATEST.... and .... you better check the bias as the reds (8-10), run VERY hot. On rating numbers: Basically, a #1 will distort sooner, and a #10 later. If, for example, with a mid range tube, say a #5, makes your amp start to break in the output section at a volume setting on the amp of "4", then with a lower number tube, like a #2, your amp would have a same sort of break into output distortion at say a volume setting of "3". With a higher tube, such as an #8, then you amp would stay clean to about perhaps "6" on the volume.
