Title: Help needed
Post by: Guy Boisvert on May 04, 2013, 09:18:10 AM

Just finished assembling and testing tested my Stereomour. The only voltage which seems out of range is from pin B-1 to OA pad.  I get 172v instead of 230v.  Should I be worried ?  Everything else checks out just fine.

Many thanks in advance.

Hello Guy,

The 172V indicates an exceptionally strong 12AT7, which is a great thing!

As that tube ages, you will notice that this voltage creeps up steadily.

Enjoy the amp!

Thank you very much much.  I find this kit building addiction so relaxing in my retirement.
