How's your build coming up Brunk?

 

Btw, would greatly appreciate if you could share your BOM from Digikey or Mouser project manager. I still haven't gotten around to deciding on the additional components required other than the ones in the BOM (this is my first non-kit build). Thanks.

Which version are you building? I'd be more than happy to assist you :)

Thanks brunk. I want to start with the BAL-BAL version.Never had a balanced amp before, so really curious!

Here's some stuff you'll find useful not listed on the BOM from DigiKey

Web ID   50252816    Access ID   66436

 

  • get TIM and power entry module (250v rating) from ebay
  • hot air station and solder paste is really useful if you have some cash to spare
  • .032 or smaller 63/37 solder, with atleast 2% flux
  • flux pen
  • 1.6-2mm chisel tip (your workhorse for nearly everything)
  • 24awg wire
  • glue gun (to mount stuff to chassis etc.)
  • chassis connectors (XLR)
  • copper foil for shielding (optional)
  • a DMM or two
  • a camera with zoom and flash or a 30x loupe (inspection)
  • a nice set of sharp, non-magnetic tweezers (not drugstore kind)

Thanks again Brunk. Will get back to you if I have any more questions via PM. I assume you have already completed yours, any impressions on the performance & sound? (if possible, pictures please ;)). Cheers.

Here are some pics as requested from a batch of the BAL-BAL and PSU I just finished. These will be for sale for those that want one pre-assembled/can't DIY and put into the chassis shown at the bottom, so if anyone is interested send me a PM!

Great to see some fully assembled The Wire amps for sale.  I wish we could have some commercial builds of it to replace the o2 amp since it seems like this is way better

Way better? Probably indistinguishable by ear, this is bulkier and isn't portable. I wouldn't be surprised if it performed better in measured test in some respects, and it might drive some phones the O2 might struggle with, but it's important to understand that the bragging rights are almost certainly all about paper specification, and that the sound will be indistinguishable from numerous other top-quality amps. After all, the whole idea of hi-fi is that the better they get, the more indistinguishable they become, and the O2, on the basis of any available evidence, is transparent.

 

I have loads of amps. More than 10 headphone amps alone, so I'm not in the business of discouraging anyone from getting another one, but I wouldn't recommend that anyone get 'The Wire' on the basis that it will be perceptibly better than an O2. What it does mean though, is that you can congratulate yourself on owning an amplifier with superlative paper performance.

Fixed it for you.

For such small mercies, I still give thanks.

Thanks for sharing the pics brunk - those board look great!  My parts, minus the back ordered psu caps, arrived yesterday, and I'm looking forward to trying my hand at the se se build.  If I fail miserably at the smd work, the possibility of ordering from you is an attractive plan b!

 

Still trying to decide on an appropriate enclosure.  Presently, I'm assuming the prudent choice for me would be something precut since I don't have access to any sort of a shop, and this is my first desktop diy build (aside from two bh kits).  If anyone has any recommendations, I'd be grateful.  Also, any chance any of you could recommend some decent, affordable hookup wire that I can buy in red, white and black?

Thanks Skeptic! I put quite a bit of work into them. I still need to clean up the flux a bit, but I literally just finished these last night lol. I piled up on the PSU caps, it was probably me that bought out the remaining stock LMAO :tongue: I have 16 left of the 3300uf PSU caps, and 8x of the 330uf poly caps. For chassis drilling, you can get by with a standard drill and some stepper bits like these;

or a router with a blade made to cut metal, but you would need a large bit to drill a hole big enough to fit in the blade, and of course some filing picks are a necessity.

 

For wire, you can get some from this place on ebay that has great prices. This is only one option, there are many sizes and lengths to choose from.

Hope that helps, and good luck!

Thanks brunk, much appreciated!  One further question - what did you go with for your IEC / fuse / power switch module?

I went with a 250v rated module with a 200-250ma (can't remember right now) fuse. The switch is built into the module itself and glows red when it's on.
