Rev. 3.3 assembly instructions - Found the info !

Postby oddur » Thu Mar 13, 2008 9:09 am

Hi
I have more or less finished assembling two J99´s rev. 3.3 I bought last year. I am using the John Hardy C990 opamps.

Regrettably I did not download the assembly instructions when I received the kits. I downloaded the current instructions. There are a few differences in the layout. I can not sort out the Initial power up and testing page. I can not find any mention of J6 and J8 in the instructions.

I need to know how the jumpers are to be oriented, both for operation and trim setting. Following the instructions I can not adjust the voltages correctly.

I would appreciate any help.

Thanks in advance
Oddur

Look at the sticky on the top of this page

Looks like it has guidance on how to use those jumpers to test/adjust the J99.
