i got the new tranny installed(its currently loosely strapped to the chassis with trashed speaker wire
; (we used to have a term like that, the last word is "rig" but it would be inflammatory and very distasteful for me to say it), and i was able to verify that yes, the amp emits sound, and yes it will be much much louder! i couldn't turn it up, at all, tonight, due to the non-rock and roll lifestyle parameters i currently find myself immersed in.
the "parasitic/ring modulation" effect is still evident on the bass notes, but i think it may be a low-volume phenomenon. as far as the Sprague can caps go, i couldn't ID one of their values due to the ink being worn off, but they appear to be different based on the other numbers that i can read.
i tried the new matched power tubes also, and i imagined maybe i could hear more EMF hum with them- but because the transformer mount is
very temporary, i did ZERO wire "dressing", and also i figured maybe a matched set of power tubes is able to transmit more hum whereas the worn/unbalanced set may have choked it off...? i do see that they exhibit bit of "plasma" or blue glow now which at least
looks cool. that is starting to seem to me to be a signature of a properly operating output tube; maybe "
plasma blues" is just one notch under "
red plate fever".
anyway, my plate voltage is up to about 220, and thats with the Full Monty of the mighty 124vac line. the cathode resistor now has 13+ volts on it. so if i want more output tube plate voltage i can use a lower value cathode resistor, is this right? the current one is 270 ohm.
oh, anyone need a 325-0-325@ 40 mA transformer? lesson: don't be shy to crank up an amp when buying it off of Joe Schmoe
