Full kit or board only is fine with me. The most important question: when will be the public release? i cant wait to get my hands on them

Got back from a road trip tonight and had a present waiting for me:
 

 

 
Looks really good. I really like the inclusion of the test and verification sheet. A very nice touch.
 
I am a bit too tired to work with it tonight (a long, long day of day-job activity and plane flights), but, I will hook it up tomorrow and let you know how she rolls.
 
BTW, this is fully shielded and encapsulated.

Jake,
those TXs look nice.  SumR provides an excellent service to those needing custom TXs.

Hello EHHA Fans,
 
I will be making kits for these and will also stock the boards.  It is nice to see all the interest in this project, as the EHHA is an amp that needs to get out there and be listened to.  I will be working with Alex to get a number of boards fabricated and they will be available in the store in about a month.
 
Talk to you soon,
 
Jeff

Soo close. Yet soo far away.
 
Edit: yeah, far away indeed. I've got a short on one channel between v- of the servo and ground. tracing the circuit for shorts, might have fried a 79L15 while soldering...

Pulled out the only two components that connects to v- pin of the servo to ground. The short still exist >.>
 
Good thing is that the short only exist in that segment, which means I could just green wire it, bypassing the short. The Bad thing is I can't spot the short in this small segment... (I now suspect that it is a direct short between the pin and the ground plane, but it is covered up by the IC adapter. -_-)
