Where to go to get a B22 nowadays?

post #1 of 18
Thread Starter 
Since rockhopper isn't building them anymore, where can I go to get one? I remember some stories of some hi-end head-fiers building them, are any of you guys still floating around?

I'm looking for a 4-channel balanced B22 for my hd650s, and appearance is important. I've seen some really nice looking ones floating around, and I'm hoping to become an owner of one as well.

I'm pretty sure YBM audio still builds them, although expect to pay a premium price.

You could also try posting in the FS forum to see if anyone is interested.

Interested to know as well!

You could put out a WTB in the DIY Forum. There are several builders hanging around who can do it. Have you thought about building one yourself? Kits are available through Glass Jar Audio.

OP stated that appearance is important and building a beta22 is not that easy, let alone building a professional looking beta22. Casework is not nearly as easy as it may first seem (as I have learned....the hard way).

What is the price range for a 4 board balanced B22 with power supply? I somehow have been rather ignorant of the B22 for a good while.

9 months ago I had no previous DIY skills, since then I've built a balanced Beta22 - as can be seen on the amb site under gallery builds. The enclosures are par-metal, I got a local shop to laser-cut panels. It can be done, it depends on the OP's state of mind, regarding the task at hand. It's a massive project to undertake, and a decision not to me taken lightly.

It should be about $500 shipped.

OK, try and walk a straight line. LOL

I was actually trying to answer Born2Bwire's question. I meant the kit from glassjaraudio for a 4 channels B22 kit and S22 psu kit cost about $500 shipped. I thought I will just post the answer without quoting him but you just happened to posted before me so it looked like I was talking nonsense.

Yeah, for the parts not including the case or the labor charge to build it. That brings it up to around $2,000.

Well that ain't gonna happen for me then. I would not have any difficulty building the boards myself, but I do not have a soldering station, tools for measurements, access to building a case (would have to hire out), the ability to match the parts appropriately from a pool like a builder would, etc.

Just some things:

Soldering iron is easially fixed as is a multimeter.
ParMetal cases like what John used are only one of MANY possiblilities (people have used biscuit tins!).
Thanks to Ti's (AMB's) store everything that needs to be matched can be bought prematched

Yeah, you can easily get a $20 iron from Rat Shack and a basic analog multimeter. That would be suitable for building and troubleshooting a simple circuit like a CMOY but I would not want to use that for a large and complex project like a four board B22 with power supply. I would want a station, a basic Fluke multimeter, and probably an oscilloscope. The parts that you can order do not include the resistors and all but one capacitor type. So one would still want to order a large set and go through and bin them to match to some degree.

What I mean is that for some simple projects, like a PIMETA or portable amp, it is pretty easy and accessible to build yourself with a minimum of investment. Get a cheap iron, basic multimeter, and a plastic hammond case or tin and a drill and you are good to go. Going to a project like this would be much easier with more investment into your tools but this is a bit hard to justify unless you are interested in doing more projects. Hard to find more projects to step up to once you got yourself a B22 though.

Too bad I no longer have access to that MechE lab that I worked at a while back. They had a machine and fabrication shop and a decent soldering station with scopes and tools that I could always just walk in and use if they were open.

EDIT: I could just jump on a commuter flight to Oz and grab johnwmclean's amp. /me goes off to comparison price between airline tickets and parts lists...

I understand where your comming from but an oscilloscope is completely unnesesary for assembling a b22 successfuly. A cheap multimeter with a diode test would be fine but small pincer probes would help. A cheap temp controlled iron would be perfect ^^
The resistors that you use are 1% metal films in order to make matching unnessesary. The ciruit is designed for good quality ~20% tol. electrolytics.

What you do need in spades is patience and endurace, esspecially if going for a balanced build.


Edit: Opsie~! To answer the OP's question, I think 2500-3000 is probably about right.
