281 clone project- taking orders now for last run of these..

So I've finally come around to finish my 281 boards. I have 4 populate, but i decided to wire up a pair first to test the modules. I have the peak circuitry built on board B, and the CA3080's are substituted w/ the NTE996.

The A module appears to work completely fine as every function works as I imagined it would. But B doesn't have any output. I've checked the wiring, and everything seems to be alright. Only my b amount pot may have the wrong wires soldered to the left and right legs. My 10V regulator appears to work fine as I get 10V across the wire from board A. When I turn on the quad mode switch, I can hear the trig inputs on B when I have only plugged in a trig source and the output plugged into the mixer out, with it noticeably louder when I switch B into sustain mode.

Also, although A appears to work fine, the NTE996 on board A gets very hot.

If anyone can give me any tips on how to trouble shoot this it would be very much appreciated.

ok-
i will take orders for yet another run of these boards as i have so many requests for them. this will definitely be the last one though, the 3080 is 2$ a piece now. I am in the process of drawing a dual and a quad board which share 4016s and use 13700s, which is what I should have done to begin with, but these won't be done for a while and in the mean time, i am going to publish the art for this board as well on my site which is gonna be updated probably tonite.

so- PM me with your desired qty's and i will put the order through soon after I will accept pre-payment as these are a known quantity and so am I by now.. Cool

I will PM you back to confirm and with total and paypal address.

thanks!

I will finally be getting around to finishing up a pair of these sometime in the next couple of months.

I have a couple of quick questions before I finish designing my panels. First, does having a "both" cv input and attenuator require any extra circuitry? Second, I noticed a few people have separated the trigger and gate inputs. How is this done?

Sorry if these questions have already been answered, but I didn't see them skimming through this thread.

Thanks,
Paul
