Very, very nice!

congrats on your amp, as soon as I get a digicam, I'll post pics of my baby.

SCHWEET work, Voodoo!

Reverse that bezel on the back and I'd advise you to get into DIYFSE

Voodoochile> Yes the Casscode current source will work on the OPA-627's in fact this opamp really benifits from this. if AC powered the Current source should do about 5 Ma. so different transistors than I specified will be required. BTY I also like The Natural Silver Finish on the Hamond cases, as well as others. Black has been around so long it is boring.

Wow, I've never seen the regular version of the case, and it is indeed quite nice looking.

Very nice amp very nice . those caps are huge! they tower above everything in there. Would you mind if I ask the uF value of those caps? btw, How long did it take you to make the case?

geom_tol: "Cosmetically you could replace those phillips screws with some stainless (or just black oxide) socket head screws, that would make it look even better IMO. " ---Wow, we are on exactly the same wavelength! I have some black oxide hex-head countersink screws to try, as well as some aluminum phillips-head countersink screws. The screws that come with this box are so cheesy in construction... quite a contrast to the otherwise nice quality of the box.

"And if there's any way you can make your powersupply dual you may want to do that since you can then eliminate the virtual ground driver circuit." ---Hehe, yes, I did make one earlier, which I'll use in another amp. I already had the onboard components on the META, as I was not sure if I was going to make it battery or AC powered. I figured it's just another degree of isolation at this point. The dual supply I made has four 1000uF caps, with a pair of tantalums at the end, as well as a slightly beefier transformer. It also has trimmer pots at the adjust pins of the 317/337 regs.

eric343: thanks for the advice , Tangent suggested the same after seeing my cmoy. I might consider that after the holidays. Work is nuts right now. As for the bezel- I reversed it on purpose, as the AC inlet is almost flush with the top of the rear panel (d'oh!), and you could see it from the front with the bezel the original way. This orientation provides a slight recessed look, helping hide the edge of the inlet. Next time, I will mount the inlet lower.

One thing the front picture doesn't show that well is the alignment of the jack/switch/knob. They are not on a straight line, the switch and jack are about 1/8" lower than the centerline of the volume knob. For what it's worth. Also, that is the 2"x4"x4" approx case, so I'm pleased to have jammed a linear reg. PSU in there. The META caps, BTW, are 1000uF 25v Panasonic, IIRC. I'll check tonight. Overkill, perhaps, especially with the line powered option vs. battery. They are 12.5mm x 35mm.

Thanks for all the kind remarks, guys.

Thanks for the info, ppl. I'm going to start another thread for that, as I don't want to get too off-track here. I have to stress that I'm no EE by any stretch of the imagination! I do understand things explained to me pretty well, at least. I will likely start that thread this morning.

andrzejpw: I look forward to seeing it. I love checking out how people case their work. I recently saw an amp housed Sheldon Stokes-style on a hexagon base... really nice for a non-tube amp.

zbuddah: It took about two hours to case it up. This was partially due to wiring the transformer in place. That is, it was not all prewired beforehand- I had it connected with jumpers, as I was not sure if it would quite fit. I have anothe Hammond box that is the same in cross-section, but 8" long. I plan on installing some sort of dual-mono buffered ultra-cmoy/meta42/I'm not sure what you'd call it, with a pair of dual-reg linear PSUs, one for each channel. It sounds roomy, but it will be tight, I'm sure.

zbuddah: Oops... those are 2,200uF caps. 12.5mmx35mm. Panasonic FC series. The 1,000uF I mentioned earlier were for another project.

Meta42ppl?

voodoochile, i bookedmarked this page! GREAT WORK!!!

Thanks, wallijonn! I appreciate your comments, and am glad you like the silver look, heh.

The PSU board is just some pad-per-hole protoboard. I included all but C5 on the Tangent META42 board, so the off-board PSU is a straight single-supply, running at 15v+, feeding the splitter on the META42 board. All else is handles by the META42. The PSU does have a few caps on it to help smooth things up further after the bridge.

I now have a pair of EL2002s on each output, and it does sound good, I have to say. I'm very happy with it.

After I case a few more amps, and get a feel for how long it takes me realistically, I might do the DIYFSE thing. I've made two C-Moys, two META42s, and an Apheared #47 in the past six weeks or so, along with three line-powered linear PSUs. But I've only cased three of the amps thus far.
