Default aleph3's almost complete!

well, for those that care, as promised, it would take about a week to get a second channel built. after two days of working, i am 90% done with the second chassis! im pretty surpirsed. i got half of it done in one night. another couple days working on it, and i can start listening.

picture 2

edit:

i had a slight problem with transformer hum on the one amp (partly because it was running so hot and probably overloading the tranny), so i decided to make it a non-issue. if you look at the transformers mounting, i am using 4 pads for each transformer. from the bottom up its: case, 1/4" rubber pad, the felt pad thing they give you, transformer, felt pad, 1/4" rubber pad, top plate. these things are SILENT now.

Looks pretty cool. Is that acrylic that you are using for capacitor "clamps"? A good-looking solution in any event.

When are you going to complete the amp as shown on your avatar? I remember you have a lot of those chassis ready to go. I'm anxious to hear your progress on those. Any reason why you were side tracked to build other stuff first?

Very nice idea those elco mounts

How did you cut the holes in the plexiglass/acrylic/perspex (don't know the proper word)??

fcel:

i have a large explaination on my website, under the aleph3 section. i basically wanted to get my feet wet with something smaller and simpler first.

after these are done, those amps are next.

Duck-Twacy:

its actually a little difficult to deal with, moreso than i thought it would be. i used a hole-saw. its a bi-metal, used for wood, plastics, and softer metals.

its very slow work, because it can get stuck really easy. i have a big 12" drill press, and it still was pretty tricky. but, after it was cut, i used a sanding drum, sanded the inside edges of the holes, removed the plastic, and its done! it does look awesome in person too. unfortunately, the cap bank covers most of it up. but i still know its there.

I forgot where i read or was told, but use kerosene as a cutting fluid and you'll get a beautifull and smooth cut, but beware. it's flamible. I wouldn't use with a brush motor tool, only inductance motor to avoid sparks. It's not explosive flamible like gasoline or anything, but will burn hot.

oh yey, very nice looking. Sorry if I sent you on goose chases. it wasn't my intent.

dieringe,

the images on the left are java. you might need to enable java. however, im planning on changing them, as they slow down the loading time of the site.

brian,

you didnt lead me astray. you helped out just fine i usually use a special cutting fluid for metals, but i didnt know if i should use anything for the plastic, because sometimes oils can melt away or errode plastics. i just wasnt sure. in any event, it worked out fine, but i might not be working with that stuff again anytime soon.
