and it lives.

I think this is my most 'pro' effort yet.

Mr. Brightside · 16 Mar 2009 at 10:55

That looks a just a *little* bit good.

Just spotted that on Head-fi, Adam. Brilliant work.

cheers, i am really pleased with it, the front panel finished it off so well. know anyone with a metal lathe? I need to reduce the depth of the knobs so i can have the same surround as the power know all round.

Nice one Adam - looks really good!

Yaka · 16 Mar 2009 at 19:02

Small request:

This is a little late, but I feel it's about time I added a couple of fuses to my receiver. It was suggested I use 2: one on my amp's main transformer, and one for my DAC's transformer.

What sort of fuse should I be looking at? Slow blow? And on which side of the transformer should I place them?

If someone could suggest suitable fuses/holders that'd be great.

adamau5 · 17 Mar 2009 at 17:51

slow blow. and then it depends on the curent draw of the amp. I doubt very much you need anything over 200ma for the dac (but then i am guessing) and then, for a 100watt amp maybe a 1amp fuse before the primaries?

p4radox · 17 Mar 2009 at 18:09

That's pretty much what I was thinking. Cheers.

Just a quick question to all you guys who have Modushop enclosures. Mine have the standard silver front panels and I don't fancy paying €14 each for the 10mm panels in black.

So how do you think the silver ones will take to a little spray painting? I was thinking a few light coats of matt black spray paint then a light clear matt lacquer over the top?

Mr. Brightside · 18 Mar 2009 at 15:01

I'm going home from uni tomorrow and so am about to order a few extra tools before I attempt building my BantamDAC. What diameter solder do you lot use for SMD work? Could I get away with 0.8mm for the DAC itself?

adamau5 · 18 Mar 2009 at 17:31

bit big if you ask me. 0.5 is better, 0.3 i find is too small.

adamau5 · 18 Mar 2009 at 17:32

founder film..... cant help but feel the paint would look a bit cak.

by the way, the 10mm panels are extremely (read impossible) to drill with good tools.

I suggest you get modushop to so the work if you go down that woute.

Did modushop do your panel then? How much did they charge if you don't mind me asking?

Hey, I'm a new user to OCUK, found out about it from saitrix (actually live in the same house as him).
I am in the process of building a Class-D amp for my uni project and have been looking through this thread, have to say there is a lot of nice looking DIY amps. Just wondering where are decent places to buy switches, connectors and case's from? I've already got all the amp modules that I need.

Thanks.

no they didnt, but it would be cheaper to get them to do some basic work than sending it off to FPE or Schaeffer.

if you have a bench drill, and good drill bits it may be achievable, but it wont be an easier job. When drill through alu that thick it tends to melt on the bit, clogging it. You cant use a stepped bit becuase its too thick, but going for a big bit tends to rip at the material.

cases : modushop.biz

switches / connectors : rapidonline / farnell / cpc / even the dreaded ******s if you dont want to order online.

hookup wire, navships on ebay.

Smeeble · 19 Mar 2009 at 12:18

Cheers for the info, had forgotten about farnell even though I bought my transformer from there.

The dreaded what? ******'s is the only thing I can think of that fits in that space.

Smeeble · 19 Mar 2009 at 12:29

Ahh, it must be the one beginning with M seining as I typed it and it blanked it out

NightSt@lk3r · 19 Mar 2009 at 13:31
