Green led 1.52v
op amp start at 15.00v but start reducing v slowly 0/v to v+
0/v v- 16.00
for both
0/v c 0.23 and 0.31
v- v= 0.22v on both
no volts on none of the other leds ? only the green led has voltage...
i know there a path to test, it will take me over 6 months in collage to get a basic understand of test paths , do and don't , if you could help me a little, i will become over joyed, and hopefully resolve the problem, then i can make some music , title of my first track will be call rob Flinn helped me ..(did i say that already)
That's all i tested,
the other pre amps i built worked no problems, and it was a lot of components , a board three modules and a op amp that sits on one...
what i think happened is, as i was soldering a resistor or other component, a resistor popped up, maybe the soldering iron also touched that part, the lead was already cut, i pushed it back and soldered it again, i can't remember where exactly it was but i have a fair idea the area it was, i tried to solder the top part of those resistors a little, just in case and to make sure there was a solid connection,
one last thing, the white cap, it has a dot on it, it didn't say anything about orientation in the build, is this correct, as im looking at mine and its the opposite from all the other Vp28 ive viewed online.. like upside down, im thinking about changing it so it looks the same as everybody else
my top guess is that is what happened and i haven't gained a solid connection, but i don't want to run the soldering iron over it a hundred times...
i will try and reflow the solder again, as i can not find anything better to do ...
