Re: Regurgitator kit Build Thread

Thanks, each output (L&R) is buffered by 5534's, and then fed via 22uF and 3K65 to output pins. I think these could be used stand alone as they are now. I basically like'd to do a two four-to-one sums from left and right signals. Perfect. Just connect the 4 x L and run into +in on regurgitator (lin...

Re: Regurgitator kit Build Thread

Could the regurgitators be used as a summing make-up gain amp? I have four input modules from an old broadcast desk, each have unbal post fader/pan L+R outputs. I'd like to sum those as L+R. With suitable resistors they could be summed and gain lifted? Or something else? Yes can be done easily. Jus...

Re: BAN Build Thread

Joe, now I am clueless. The new trimpot did not help, and the old one was faulty. But still I did not get the 16V. Now I removed all the #-parts and put it into normal 48V mode. There should be between 24 to 48 volts on those 470µF caps on the + side, right? Near that #10k resistor I have very close...

Re: BAN Build Thread

Thank you.

Now I have two boards, one singing beatifully but with the another I cant get correct voltages. Either I have broken the 10k trimmer or the #681 is faulty.
The voltages are now: 0v - TP1 = 30,8V, 0v - TP3 = 1V, TP3 -TP1 = 29,6V no matter how I turn the trimmer.
What you say?

Re: Correct voltages?

Hello, I am almost done with my new BANs with gar2520. The 10k trim is set to 15V. Is this ok? Just leave the 10k trim pot at the rear of the BAN PCB in it centre position it comes set to new. No adjustment is needed with a 2520. To re-centre pot turn until hear clicking and turn back 12.5 turns. C...

Correct voltages?

Hello, I am almost done with my new BANs with gar2520. The 10k trim is set to 15V. Is this ok?
The 2604 is fitted but the 2520 is not and the phantom led is very dim. I'm getting correct 48V on the input but between the phantom legs it is about 20V. Ok?

Re: BA BA2 BA4 BAD Dual99v Build Thread

Hi Joe! Almost there, but I want be sure of some details before booting this thing (BA with JML14 + Hybrid + 315mA SMPS). - #10k fitted and extra wire - #BD681 - a small brown cap, reading "281". Where is this supposed to go? On a CLFixed I have "221". - There was not a RG (68 ohm resistor) on the ...
