The transformer in one of my pair seems to be too fat to fit comfortably in a rack with other modules. The other unit seems fine. Has this been a problem?
BTW I sent you a PM on another matter. Thanks

Re: LA500A opto comp leveling amp BUILD THREAD 500/51X
Why haven't the build instructions been updated to inform the builder that it is okay to use the other holes? Am I missing another set of instructions somewhere? I just finished my pair today. The holes are not for the kit but will work. They are for our built production LA500A modules so we can pl...

Re: LA500A opto comp leveling amp BUILD THREAD 500/51X
Can you clarify what exactly all the jumpers are for in the builds?
Also confirm that there is no need to calibrate as a stereo pair if I ordered 2 units as a pair. I received the specially marked optos and installed as indicated.

Okay, sorry I refer that was as the Mac. Had to de-solder the meter to remove PCB and get shots of the board. I've attached photos and will send the voltages from the op amp on the LA500SC PCB after re-assemby. IMG_5285.JPG IMG_5286.JPG This photo shows the opto leads have been soldered in to the "...

Re: LA500A opto comp leveling amp BUILD THREAD 500/51X
In some of the pictures the builder is holding the component in place with a thumb and soldering with the other hand. I am curious as to how one can apply the solder in such a manner. I usually have solder in one hand and iron in the other while PCB is laying on a flat surface. Thanks. :?: :?: :?:
