hmm whats up with the new "emoticons"....i think i prefer the "lo fi" ones.
anywho, i picked up a homebuilt PP 6aq5 guitar amp from some tinkerer. it employs two 12ax7s and a 5y3 rectifier. it has a volume, super high treble(or presence?), a mid, and a low control. it also has a couple of toggle switches, i think one of them jumpers pins on the power tube sockets for trying out different tube types, the other one i don't know. everything is unmarked.
anyway, the amp sounds pretty good, it doesn't buzz or hum at all. but it is very quiet at full volume, seems to be about 1/3 of what my 5 watt valve junior does, and on the low notes i can hear a semi-tone, almost like an octave thing going on. its subtle but definitely there on the lower guitar registers. i'm very pleased with the amount of low end, and the amount of tone control i have over the mids and highs too.
i'm wondering, could that parasitic/overtone effect have an effect on volume? the way i see it a PP (2)6aq5 should comfortably put out well over 10 watts.
the output transformer is physically tiny, the smallest i have seen i guess.
anyone have any off-the-cuff ideas why its so quiet? the dude gave me a schematic but i don't think it applies; the preamp tubes are different on the drawing, among other things.
i realize i didn't supply enough hard data here for troubleshooting; i'm just soliciting a quick idea or two
