Topic: digi-mod ua-5 to jb3 via optical help

[dklein]

i had an analog source in the back, the peak light was flickering, but i got nothing through the headphones with the monitor switch both on and off and the knobs all the way up

This shouldn't be.  No part of the mod should interrupt the monitoring unless you slipped with the solder.  If you can, hook the UA-5 up to a pc (thru USB), load up the drivers and try recording something.  I don't know if the UA-5 peak light is driven before or after the ADC so we don't know if the signal is reaching the ADC or not. 

If you have a digital camera, maybe you could post a really close up pic of the jumper area?

...did the UA-5 work before the mod?

I know this may sound stupid, but did you turn the phantom power on?

hooked it up through the usb and got nothing on the pc  
I don't have a digital camera but i am almost positive the soldering is correct, not pretty, but right.

maybe i got a broken ua-5, i tested it and it was playing the music from the computer before the mod, but it doesn't work now.

i am so lost....

edit can't spell, and +t's to everyone that helped (when i can)

do some continuity checks with neighboring holes - especially the little group of 3 on the left side of the jumper (not the one by R35...the other end).  Magnifiying glass or loupe required!

yeah, that stops working if you did step 1 properly.  Too bad you didn't try putting some signal into the UA-5 just so we'd know if we're trying to chase down something new or not.

i had a meter, but it is mia, i will try to find one...

edit: i will have one tomorrow

[jdh263]

well, its monday and still no meter, i am about to give up on this thing, if anyone can help me i will get you back anyway i can.

after walking away from this project, i decided to try again.  I took the jumper out and re did it.  tinned the hell out of the wires....and now IT WORKS!!!  i guess it just needed a break.

thanks for all your help, +ts all around

Sometimes it helps to just walk away.  especially soldering small things.  left a project on the bench for months with nothing but problems and just picked it back up a few weeks back and all the problem mysteriously were fixed after i re-did some of my work
