Tube depot for the bits and pieces and turretboards.com for the , you guessed it, turret board.A my friend helped me snag the parts needed from the schems / layouts at ceriatone.

I hope it still sounds good. Link to comment Share on other sites More sharing options...

Members newholland Posted April 21, 2008 Members Share Posted April 21, 2008 board's pretty elegant.. man i love turret boards! what're the big yellow caps for? i recognize the orange drops.. but what're the others, and what're they for? Link to comment Share on other sites More sharing options...

Members newholland Posted April 21, 2008 Members Share Posted April 21, 2008 d'you guys ever use oil caps in yer builds? i know i get a lot of use out of 'em for hifi stuff-- but it seems like even high end builders use electrolytics and film caps in their amps-- i almost NEVER see PIO's in guitar amps! too soft?

Members trey85stang Posted April 21, 2008 Members Share Posted April 21, 2008 Im building a jcm800 right now as well... im using an epiphone socal 50 as a donor amp. I still need a few more parts to get started though which I plan on ordering this week I hope. Link to comment Share on other sites More sharing options...

'cause i understand the guts to a certain extent-- but there's not any amp nerds around here that're too hip on explaining what circuits do what, what parts do what inside circuits, and how it all goes together! i've got bits and pieces-- but i'm a speaker nerd... i can't die from making crossovers!

Members newholland Posted April 21, 2008 Members Share Posted April 21, 2008 there's only so much time in a day... if most folks could get into EVERYTHING they wanted, what a life. plus, it'd pay to be independently wealthy enough to not care if you blew stuff up... that's not MY particular problem for sure. you DO need some scratch for parts, measuring equipment, and amps too.. which you don't necessarily risk yer number one gigging amp to experiment on..

I'm working up to it. I would like to maybe use this as a platform for me to get a grip on at least some of what there is to know. At the least I would like to be able to fix it if something pop's or tweak / hot rod the settings you know. That, to me, would be the {censored}! thanks for the comments / encouragement.

I know some of you have been here before and im glad my scrappy little turret didn't make you too much....but there's still time! I was just kidding around, I just found it amusing how many people say they "have a friend...". Kinda wish we had more amp nerds here. But seriously, the best way to learn is with a good book. This place is actually pretty bad overall for getting good tech info (there are a few exceptions) and there's really no short cut to learning this stuff, it just takes time to understand. With all the books that have already been written, it's kinda silly to expect someone to explain it all in a forum post. You can get specific questions answered but learning the fundamentals is something you really need to sit down and spend the time reading up on. BTW, the turret board is the easy part, wait till you start wiring up the chassis Seriously, looks good so far. Stay patient, pay close attention to detail and make sure everything is wired up correctly and you should be fine and end up with a very nice amp. Good luck Link to comment Share on other sites More sharing options...
