Post pics of your builds.... - Page 408

LIES ='(


Hehe I knew there was a reason I bought that new drill press~


After seeing your column of the t2 bom...

I have lots of corner extrusion here as I was counting on having to re-enforce the bottom. Guess that's a given now

I wouldn't either but with a 10mm front panel there is enough material to drill and tap some holes to provide extra support. I did this with Duggeh's old F5 which I'm rescuing and it worked well even with the rather large transformer a couple of inches from the front.

I couldn't live without mine.

I'm easing up a bit with older age though so I can live with RN60's.

Well I have worked out that I can use a 1.5" and a 1.625" standoff mated together to provide almost the exact internal height of a 2U chassis.... should help couple the top and bottom nicely.

That should certainly help.

I have a question about the parmetal cases someone here might be able to help me with. If you look at the group build here (The β22 Stereo Amplifier) the parmetal case has a detachable front and rear panel. But when I look at other builds using parmetal cases like on page 403 of this thread (Boinger's silver case) the rear is just part of the case. Maybe I'm missing something obvious but I'd like to know what case the group build used because I'd like to FPE a front and read panel. Thanks.

It’s a custom order the inside support piece for the front and rear has a rectangular cutout (as per the standard front). Doesn’t cost much either, mainly the extra front panel for the rear.

next level of progress on my 3ch b22:



I have some gold molex connectors up front. I wasn't even aware they were gold until after they arrived (I went with amb's bom and didn't think twice about it)

there's still some sticky tape residue on 1 or 2 heatsinks. all boards have been flux-cleaned, though.

last step is to build 3 wire harnesses that connect to the gold molex headers and a calibration run to set bias, offset, etc.

That is darn scrumptious linuxworks, such a straight up and clean build so far.. I guess that's what the backplane was designed for though.

What I'm trying to say is nice work and thanks for sharing.

linuxworks, looking forward to a comparison between your 2 channel.

I visited the M³ during spring break, but buyer's remorse got the best of me and I have sold it. I am revisiting it again, and I have casework and some bridges to fix before I'm up and running. Q6- is a concern, but I think I'll be just fine.

just finished building this CMoy yesterday night, shipped it this afternoon:














pardon the ugly pictures

The work is great.. I always want to build a amp for myself but I am electronic idiot... I wonder how much will it cost to get someone to build this awesome amp for me..

thanks for the nice words, outdoor

fwiw, those 3 boards took me 2 full weekends to build. its a LOT of little things that add up. the time really gets away from you

add in even more time if 'looks matter'. I tried to keep the resistors all pointing the same way with readable value/lables on the top of the part. I tried to make all the top and bottom solder pads look nice and shiny. I did at least 2 full passes of defluxing and board cleaning. I must have desk-checked the board for a total of half an hour, each board, just total 'staring time' to visually inspect things.

I'm not sure how fast one can be built, but on the 'take your time' scale, I'd figure 2 full weekends of JUST soldering and assembly of the raw boards. I have no idea what I'll do (yet) on casing it up but just the soldering, itself, takes a lot longer than I expected.

then again, no one builds a b22 as a 'slam job'. *everyone* takes their time doing a build like this. rushing it could mean an expensive lesson (been there before, myself!)

WOW is the only word that can come out from my mind.... Keep me in mind when you are letting this awesome amp away... I am the second owner as long as I can get a 230VAC/50Hz PSU to go with it..

Hey all you have to do to make the PSU work is rewire or replace the transformer depending on the type used so please do not let that stop Linuxworks from donating that amp to you
