What a great Idea Pete.

really nice work,
it would be great if someone could provide the PCB's.

 

[Whoops]

any news on this project?

thanks

500 series version?

Pads for Jensen 115ke & 115epc, Cinemag CMMI10pca &  Lundahl 1578 transformers. I used a 5532 balancing output stage, added phase, phantom & pad switches.

Anyone like this idea? Comments please....

Peter

Looks great Peter! I am defiantly wanting a few in the 500 series so yes PLEASE!  ;D

I have been tweaking the layout that I had originally posted and as soon as I can I will be making a prototype to test.
Also I have been using digi-keys BOM tool to make kits that you can order directly through them.  Or, you can source your own.  So far there are only 2 items that you will have to purchace from other places.  Once everything is tested I will post to gauge interest for a non-500 series version.

I have a prototype board on it's way from futurlec so i hope to have some progress with this soon. 
The version I have Prototyped is the single 5534 with a THAT1646.  I have a layout for the dual 5534 but have one question regarding the schematic.

On the schematic from Wayne's site http://www.ka-electronics.com/images/SSL/ssl_82E01.pdf it shows a 1M resistor(R73) connected to +VE.

Now on this one http://www.n-tosch.com/tec/82E001/82E001_1.gif it does not show it.

So the questions are:

Which one is right? 
Is the 1M actually connected to +VE? 
Am I understanding correctly that +VE is the positive voltage rail?

Also which version is more desirable?

Thanks,

-Casey

Some prototype pics

Sounds really nice. First mic pre that I have ever used a Jensen input transformer, big & ballsy.

now, what to do with all those space left?
may be include a HiZ plug in?  ;D ;D ;D

Oh you bastard! This is proving to be more difficult than I thought....

Peter, it is only a jack, a HiZ Plug-in and a relay before the transformer ;D

Thats the easy part..... Moving all the other stuff manually is a right PITA!

Soon to be done, though

I know that  
I often start from the beginning instead of moving around :-[
now, where is your Logo for the Alliance ;D ;D ;D
or should I use the bizzar one?

however, the HiZ will be a nice addition, thank you

Oom, that statement is so loaded! LOL. Great chatting earlier today, looking good here!

Cheers

Very nice job

 

[peterc]

New version with HiZ DI option, or (as in the pics), an onboard chip DI.

Looks good!

 

[[silent:arts]]

Peter, very nice!







only one thing I don't like
don't put the jack socket over the gain knob (and the VU LEDs)
the Guitar / Bass / Synth / HiZ cable will always be in front of them ...

good stuff.  If you're going to manufacture pcbs/kits I'm in!
