steve, i actually found 2 mullard 12au7s with the square getter and marked as k61 b6h (supposedly the best ones) but one has some crazy hum and no sound in the left channel and the other has very marked channel imbalance in volume. nebby and i were getting super excited over it last night in chat. i was going to wait for the tube tester on monday but i just plugged them in to see how they were and was disappointed. the raytheon 12au7 seems to be ok.

im planning on listening to it with the sprague caps for this next week and then putting the stock ones back in to see what changes. however, the bass was virtually non existent with the original caps. at least to me. rather i was actually disappointed. put in the sprague caps - bass got nicer. changed the sylvania 6080wc to a rca 6080wc - bass got waaaaaaaaaaaaaaaaaaaaaaaay nicer. but along the way, the overall tonality got a little bloomy. changed the supplied 12au7 (dont even know what kind it is) to a raytheon 12au7 and midrange improved by a few notches. much more detailed. more liquidy. reminds me of my old extreme.

i wish i knew what all that meant.

i wish i had your kind of patience.

thanks for the tip nate. should we be looking in the amp area or the tweaks forum?

plugged in an rca 6080wc tube that i was given by the nice gentleman upstairs. the bass with the 650s is stupendous. downright silly amounts of bass. a little tightening up would help but waaaaaaaaaaaaaay nicer than the jan 6080wc that was supplied with the kit. i can feel the insides of my head rattling on "poem of chinese drums" by yim hok man. still looking for a bit of mid range sparkle. nice and smooth but would like it to be more liquid. perhaps even a little bright. (coming from someone who hates anything bright)

bleh. that picture makes me want to get a doggy hope you are having fun with her steve congratulations.

hell if i know, will send an email to bottlehead and see what they say unless someone here can say that they are substitutes

I dont know what luvdunhill just said but its a 2N2222A transistor...quad 2 or something or the other. need 2 of them thingys

unfortunately the leads are all gone. i will end up just buying 2 more (anyone have an extra pair lying around? will pay for parts and shipping obviously. shipping with digikey is more expensive than the parts themselves...). i am more scared of having done damage to the board as i am sure that will be a much more expensive replacement if required. here are some pics. upskirt ones later when i turn off the amp but as of right now the toones are playing so dont want to turn it off sounds mighty nice.[ATTACH=CONFIG]3572[/ATTACH][ATTACH=CONFIG]3569[/ATTACH][ATTACH=CONFIG]3566[/ATTACH][ATTACH=CONFIG]3573[/ATTACH][ATTACH=CONFIG]3567[/ATTACH][ATTACH=CONFIG]3574[/ATTACH][ATTACH=CONFIG]3568[/ATTACH][ATTACH=CONFIG]3565[/ATTACH]

so i screwed up the 2 x 2N2222A transistors while trying to put together the speedball kit. instructions said to leave some gap between the board and the transistor. mine are touching the board. should i just get new ones or is it ok for them to touch the board? also, installed sprague 470uf 200v electrolytic caps for output caps. bass is nicer. but overall tone has gotten bloomier.

already reading the build log >< i was curious so i went back to my old t43 and plugged in the amp into that laptop. funnily enough less noise out of the soundcard in that laptop than my 3 month old t410...

gaaah nevermind the noise...its the age old problem - my source. just tried my old pcdp. absolutely no noise that i can hear with the central air running in my office. slight grain with the volume turned up all the way but i might be imagining things. guess i have to find me a dac to build. a side note - the top plate of the amp is REAL hot. have to move my fingers after ~4 seconds. is that too hot or regular for a tube amp? 2 thumbs up with my pcdp. now i know what you were talking about steve (iron) i cant imagine it replacing a zana but for 300 bucks im pretty damn happy. 200 bucks actually since the speedball kit isnt installed yet. *off to find a dac to build*

i put the whole thing together yesterday (everything besides the speedball). spent maybe 5 hours going over everything 3 times. got everything to work the first time around. sounds pretty nice. bass is just a wee bit lacking but i think a cap change might help in that dept. nice mids. questions now - amp gets very noisy past the half way mark on the volume knob. im not experiencing the "black backgrounds" that most others seem to be experiencing. buy different tubes? resolder stuff? reroute wires? suggestions would help.

hbd sir.

have a great day matt. happy bday.

damn. sorry for both of you however, glad that nothing (bad) happened brent.

that badge is swanky. nice work.

Happy Birthday to one of the nicest people around town!

bloody hell. i didnt notice the motorola on the left or the verizon on the right but the way it is photographed it looks like its rather huge...if i had to bet i would say ~7" diagonal. looks very nice.

what is that nate? ^ looks mighty cool. universal remote of sorts for the house?

i shall find out soon enough. hopefully. from what i have read on the bottlehead forums so far, to be able to accommodate lower impedance phones, the output capacitors need to be beefed up and depending on the capacitor, a few resistors need to be changed out as well. need to go over that info again before i start building. if anyone would like to do a gb of sorts for the caps please keep me in mind. or let me know in case you would like me to run it. ps. 650s otw too now about that dac...

happy birthday sir.

what the hell do you need for that job other than the ability to lift 50 lbs? surely you can do the meet and greet stuff.
