Hi, i've just finished my 1176 RevA ;D and i really wanted to thank all of you !
Of course i've encountered some(a lot !!
![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
issues and of course, as it said in the beginning of page 1 of this topic, i've been reading almost the 100 pages to find ways to continue the job. Here are the details, so maybe it will help a few (i hope)
-I thought my first issue was the calibration step 2 when i couldn't null the TP10-TP11 to 0vDC! so i've double checked the Pcb, the wire, everything and found that 2 of the R44 pins were making contact. At this point i tried to uncontact these 2 pins and finally get this contact off....but of course that was not a good idea

.....
-so after that and a lot of forum reading, i realized that i wasn't doing calibration step 1 in a right way. As the "populating Pcb" chapter says i pre calibrated all of the bourns trimmers to 1k and i didn't want to go full CW as the calibration step1 says...once i've done this, guess what ? calibration step 2 was successfull too!!!
-but of course in calibration step 3, this bloody R44 trimmer couldn't make the Vu needle move
![Mad :mad: :mad:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
and this is the point when i understand that this weird contact between 2 pins of this R44 trimmer is normal :'((page 109 of the topic i think, thank you zylvia !!)
so this morning i 've soldered a wire to make these 2 pins happy and everything was fine, even the calibration step 3!!
i've been checking the voltages all along the building and calibration process and it has helped me a lot to be almost sure my problem was in the GR Pcb section, around Q12 and Q13 and now that everything is ok, the voltages are too!!
one last thing was a weird noise and Vu peg that my output knob created at 9 or 10 o'clock and i found the answer in mnats faq, just had to get the output wire away from the Pcb....
well, my RevA is fine, took me a week to complete this but i'm really happy, i think i've understood a lot of things doing this for the first time instead of recording or mixing, so....
Thank You Guys 8)
