Roll Call: Who's building, built, or thinking of building a beta22? - Page 212

post #3166 of 3173

I've always wanted to hear a B22, and figured the only way was gonna be to build my own.

It sounds great, and is dead silent.  Just burning it in now and making sure everything is working as intended.  

 

I was curious where you picked up the transformer for the switch circuit. I bought one of the mounting boards, only to discover that

the trannies for them were unavailable. Thanks.

Allied Electronics.  Mouser and Digikey didn't have them.

Hi Funch, thats a nice build. I like the unbilical and the cases. Where do you get those umbilical plugs and how many poles are they? How bot the cases, are these from ebay?

Funch can correct me if I am wrong but the cases look like they are hammond cases (you can find them on mouser, digikey and the whatnot).

 

The ambilical cord are called speakon connectors and they can be found at redco.com I believe they also have something called powercon which is also similar.  (both quite expensive for connectors as they where made for heavy duty dc use).  I honestly just suggest using something simple like a 3pin xlr.  Much cheaper connectors and works just as well.  Just make sure that you don't mix the connectors up with your balanced input (if you plan on using such a thing.)

Correct-a-mundo. Hammond 1455T2201BU

 

I don't remember if I used speakon or powercon tbh. The joys of getting old. I considered using XLR's, but decided to

go with the ones I used as I hadn't ever used them before. Were I to do it again, I would go with XLR's.

 

BTW, you would need to use 4-pin connectors; 3 for the power supply ( +, -, ground ) plus a separate ground wire from the PS

ground to the headphone jack.

Hi all,

 

I'm seriously considering building one of these.  The only DIY I have under my belt is some cables and a Project Solstice kit.  Do you think something like this is too much to take on at this point?  I think the soldering doesn't look too complex -- it's mostly the wiring, mounting, and various options that intimidate me.  I suspect that if I take my time and plan everything exhaustively, I should be able to pull it off.

 

Zashoomin, you should know that I was partially inspired by your chat with Tyll.  I'm bummed that I didn't get a chance to listen to yours at CanJam.  

 

Random question (pre pre planning):  You have a Balanced and SE port on the front.  Are you doing the 4 board thing where you can also do two SE amps (and then just doing one SE amp)?

 

Thanks!

The steps are different for everyone.  I think that with enough patience and help from the amb website that you can build one.  I think you will find the soldering to be no problem at all and the easiest part of the entire process.  The casework and wiring will most likely take the bulk of your time and effort.  I know there are a lot of options, but when it comes down to it there aren't a million options.  For the first project I suggest you keep it "simple" or at least try to.  Though can you plan, you will find that there are many things that you would have never thought of as needed.  

 

I am glad that I got to inspire at least one person.  That was the goal :D.

 

Ya I am doing the balanced and SE port thing with just one SE amp. The beauty of that setup is that with a balanced or SE source, you can output to single ended and balanced headphones. (though with a single ended source the output won't be truely balanced, it will output to a 4pin xlr...because I dislike trs jacks.)

 

Anyway good luck with your build and if you have any questions please feel free to ask as many as you would like.
