RE: OK- its an older 12-tube model

Posted by ChasLieb on September 28, 2015 at 18:52:46:
Just to be clear, I pulled all the tubes including all 6as7 and all 6sn7 before measuring. Do I need any tubes to be in place to do the measurements? Also, you say the two banks are six left and six right, do you mean that drawing a line down the center from front to back, the two rows of six are not divided into each row, but instead comprise two rows of three tubes on the left and two rows three tubes on the right? This makes a difference for me as to how I balance the power of the two banks against each other.

I did not originally measure the other tube sockets other than the end two on the right and now measured the two sockets on the left and got the same 410v.
