Hey all, long time lurker, first time poster. But the weather here in WI is getting ready to go full-on winter, so it's time to stop building speakers in the garage and start looking towards indoor projects.
I've been laying out a combination of a Cmoy (or maybe the JDS BBcMoy), a Tangent cross-feeder & BantamDAC all in one box. I realize the cMoy is uber-basic as amps go and maybe it's all lipstick on a pig, but I was planning on trying to keep the wiring as modular as possible. Then, if I got the urge to upgrade, I'd just pull the amplifier section, cut a few more breathing holes in the chassis and swap in something beefier. Modular should also help me keep the projects "separate" in the box so that, if the crossfeeder doesn't work or whatever, I can always just bypass the offending module and still make sound.
I was also going to add an additional DPDT rotary switch as a 2-way input selector and then wrap the whole thing in a wooden chassis with nice fat wooden knobs for the various pots and selectors. You know, for a warmer sound.
I've done a number of electronics kits and DIY soldering projects, so I'm not too worried about the actual assembly. I am, however, a real rookie where power supplies and amplifiers are concerned. I was going to run the cMoy off a linear regulated wall wart and allow the BantamDAC to power itself. I also planned to run an iPod dock in via the 2nd input.
Put simply, am I going to have grounding issues? I *think* that since the wall wart is of the linear regulated variety, I shouldn't have problems. Then again, as a speaker builder, I'm used to big fat passive components not directly connected to AC.
Let me know if you guys have any advice for the rookie builder.
Thanks all!
