Moreplay Upgrade / Slight channel imbalance after installing the upgrade [resolved]
« Last post by heavycowboy on June 27, 2025, 11:18:16 AM »Hello,
Just finished installing the upgrade. Sounds wonderful! More of everything and smoother to boot. However, I now have a slight imbalance between channels with the left being quieter than the right. I've swapped tubes, cables and changed sources to no avail. All of my voltage checks were in range except for a slightly high B+ Reg value.
Here are my results:
6U = 130.4V
16U = 135.1V
B+ Reg = 188V
4U = 8.02V
14U = 8.05V
How would I go about measuring if there actually is an imbalance? And where should I focus my attention when looking for the problem?
Thanks in advance,
Todd
