Pabbi,
It must have been 25 years in one of my high school math classes that I last saw the proper use of the abbreviation IFF.

As for the use of dovetails, a good finger joint is even stronger and very pleasing to look at if done correctly. They are very labor intensive, but only require a table saw and proper jig. I built my finger joint jig from some scrap wood and an 8/32 threaded screw. Takes a few minuted to setup, but works very well.

Agreed - just haven't taken the time to set one up, though I will now that I have a proper table saw again. Oh, and the hole is plugged - results posted tonight, then after finish - not perfect, but, acceptable.

As a reformed coder, I used IFF in C or Delphi / Pascal... or was it COBOL? ;-)

OK, the plug is in and perfectly flush, but the darker sawdust fill makes the ring exagerated - hoping this is abated somewhat when the oil darkens the wood. Amazing how different it looks with components, eh? I will always be a function over form guy anyway, since it really is about how she sounds.

Not bad Pabbi, it'll probably look fine once finished. And where did you get that cool perf sheet?
post #200 of 400
I think it was Online Metals, where a 2' x 3' sheet was about $40 shipped - this is .10" or .125", so plenty substantial to hold the 6lb toroid. May redo the top, as I didn't have enough material, IF I cut down the heatsinks by 1" to all fit inside, depending on the overall heat.

Still considering whether or not to vent the sides.

The front will be a challenge as i couldn't route a channel like the top, so suggestions are welcome, but, it has to vent the tubes heat. Thinking possible an aluminum grill grate - just something to keep fingers and paws out.

Pabbi, that option ‘c’ stat amp of yours looks pretty impressive, power wise it appears very um… potent (for lack of better word)

I don’t know what the ideal range or acceptable internal temps inside an amp should (read: safe) however do you know roughly how hot the case and components get the way it is?

Yeah it’s unfortunate the panels have been glued and bit more difficult to machine. Would you consider venting the tubes from the sides instead of front? I was going to suggest route/cut out the side panels and mounting pieces of perf sheets or add grills on there from inside.

Well, that is the great question - how much heat? The designer will actually be looking at this today, but the heatsinks will probably get 85c, and the tubes are the great unknown. I am using .20 aluminum on Option A, which was designed as part heatsink, so the wood really is not optimal for this amp (a VERY high powered stat amp).

In the end, the heat may simply be too much, but I am hoping convection with the vented top and bottom will work for getting it running, but maybe not for extended listening.

Maybe some mercury/cadmium/telluride heatsinks like they use in military aircraft would help.

And, done... except the front cover...

And, circuit sanity

x2!! I like those dark side trim/bezels they complement the knob well.

How does it sound, and so did it get very hot?
post #206 of 400
Nice Pabbi, that front came up very nicely
post #207 of 400
Actually still waiting on the jack (custom manufactured in S Texas, en route), and having to get an assist on a buggered attenuator (kinda one of my recurring themes). In the meantime, I'm ordering more perf AL to finish the top correctly.

Guessing another week, or so for power up.

Wow zkool448 your cases are the most sleek and amazing I have seen, better than any marketed retail product for headphone amps! I would love to build one like the soha, or CTH, the knob is amazing with it going over the wood, and just the overall detail for ventilation OMG woodgasm. My uncle was a underwater welder and has alot of woodworking tools. I might send him some stuff to do. If he can get it done fast enough. THANKS FOR THE EYECANDY!

hahaha many thanks doyouright

I get a lot of questions with nice comments about the knob and where I get it from. It's a well-made solid aluminum from a seller on eBay.

In fact I ordered 2 more for the Bijou that I'm building next. cheers.

CANT WAIT TO SEE THAT! First time Im anticipating a DIY build. But yours are the best! Man I wish I lived near you so I could have you be my teacher in this.
