holidays

i've been on holidays,

should be back home in a couple.

just ordered more parts.

british 18 watt

cobalt

my friends get drunk and go to shows.

one grabbed me a pic of johnny playing white thrash.

white thrash

well there she is all buttoned up.

buttoned up.

well,

i finished johnny's amp, it sounds fucking awesome.

have some pics of it with its cab and logo. but i don't have my camera with me. johnny picked it up earlier than i had hoped he would. so i never got to crank it full throttle. i'll leave that to him so no sound clips and i'll probably only get live ones now as i don't think he'll let it leave his sight. well... that is unless there is any problems with it that i need to rework.

i'll post some pics of it soon, and i get some live footage of the amp it action.

its pretty loud. 

i am a little worried about it being full throttle as i never had a chance to do it myself. i had it on a dummy load and it seemed fine so here's hoping i am not an idiot.

so now i have a hiwatt clone to build for myself. the uphill challenge keeps getting steeper and steeper.

progress

well i made progress in my head anyways,

i fix the drive control. how? well i check the switch for continuity with my multimeter, and that didn't even help. i had to take the switch apart to figure it out. stupi stupid stupid. but you gotta do what you gotta do.

so next up. i think i have tracked a whole bunch of the problem down to the negative feedback loop (nfb) but this is just in my head. when i get home today i will work on that. i am hoping it will just be a reconnection. if not i'll reroute the leads from presence control to the impedance selector.

if that fails well then its on to the master volume.

there is still miles of hope, as everything is working nothing is smoking or blowing. its just minor signal issues that come with the joys of building amps!

yay!

setting sail

well had to sign off of my work.

strap on a badge. and she is ready to go.
thanks reagen, for cutting these plates for me on the fly.

moving right along

i feel like such a dummy, this is such a complex build and i was just so involved that i forget so many important shots.

anyways heres a close up of the impedance selector. this switches are weird and they are tricky too.

a shot of the buss bar grounding system. and the drive selector pot. again this is a tricky little switch. and so much so that i am having trouble get all positions working. but with some more playing around. i'll get it worked out.

heres a better shot of the same thing. the 40 uf caps are pretty big and intrusive. i'm going to look around for some better ones and switch them out.

i'm not a huge fan of how they hang out the board like that.
heres an overhead shot of the whole chassis. every is wired up and going good.

the amp has power and producing sound. i still have some bugs to work out high gain amps are tricky. one wire moves a millimeter and it could totally change the sound of the amp.

there are 50 voltages to check on all the tubes.

everyone checked out perfect that is a really good thing!!!! 

so it practically done.

just got tinker with the glitches until i get it perfect for johnny.
