Okay, I've read every post on this great forum and haven't found a definitive answer that will let me sleep better tonight.
I just finished my first build of the VP26. Like a few people here in the thread, I also noticed the weird issue of the moving numbers on my Fluke multimeter when I got to the final step of checking the ohms of the op-amp sockets.
I have a nice Fluke 179, but I might very well be using it incorrectly! When I set it to ohms and touch the different sockets of the op-amp, the numbers are moving up. Is that normal? My Fluke is set to auto range.
I also noticed that the readings change depending on which lead of the Fluke touches which op-amp socket. For instance, if I touch the red lead to the o and the black lead to C, I get a reading of 1.6M that continues climbing from there. If I switch that around, I get a reading of -1.35M.
I want to make sure that, as of this point, everything seems to be normal. Here are my readings:
-V & +V = starts at 200K and climbs
-V & C = starts at 1.06M and climbs
+V & C = starts at 168K and climbs
C & O = starts at 1.6M and climbs if the red lead from the Fluke is on the O (like I mentioned)
+V & O = 480K and climbs
-V & O = 1.2M and climbs
I'm definitely not an electrical engineer, but I'm good at following orders. I was pretty thorough in checking the solder joints, and I organized all of the resistors with my multimeter, so those are definitely working and should be sorted correctly. I can't imagine I'd have any problems, though if there's one thing I've learned from reading this thread is that people with more knowledge than me can misplace a resistor...
Anyway, before I take it to the next step, I just wanted to get a confirmation that the moving numbers thing when I was performing the first check was normal, and that the numbers I posted look to be okay.
