The documentation is amazing.

is the opto3dc something that will be out with the opto3 or is that release far in the future

It looks like the Hammond 369JX will be a suitable replacement. €65,00 instead of £96.

You need 250v-0-250v secondary windings @ 40ma or more, and 6.3v CT @ 2amps for the filaments.

COOL Greg! Your V2 got me back into DIY. When I started here on this board. Thanks to you I have met and hopefully not offended anyone with my ignorance. But have learned tons about audio electronics.

(Long way to go) Lemmie gonna slap ya for the crooked T4 ;)

Hope you are doing well! Best wishes.

I use my version 2 on a daily basis. And it delivers time and time again. Thanks for the work involved in design and also documentation!

hi there , thanks so much ,

ah ran out of t4bs so i used the ua one for this shoot ,

the drip t4's align square :)
.

the opto 72 should be released in 2 to 3 weeks, pending a quick revision.
and the manual for it .


send an email for price info ,
did a small run of 25 boards , so i had to add 10$ for this batch .

originally this was gold plated , then i did some research on how gold doesnt take to solder very well ,  grrrrr.


the dc version with the filament transformer , is having a metal can made
for it , (rf shielding )
but it should be out in the coming month .

best ,

limiter response
« Reply #15 on: July 22, 2008, 01:36:59 PM »
i'm ordering my parts now and i'm wondering if i should pull the limiter response pot out to the front.

what is the limiter response pot for?  is this for fine tuning the attack/release?  if so, it seems like this might be a good thing to have on the front.

Covered before...

Consensus = don't bother. Leave it fully clockwise, it doesn't really do anything good that you'd want to play with.

Great man!

Are there any plans of releasing a dual version of this? Stereo LA2A!

Purusha is selling dual cases but when is the PCB for sale? Any info will do.  :thumb:

Closed I'm afraid.  

You could ask to be put on a waiting list perhaps?
