Hello everyone, It looks like I need some advice from the experts. After years of slowly collecting parts, working on other projects, and procrastinating--I finally built a Morrison Micro SE DC 2A3 stereo power amp. I followed the widely-available schematic very closely, with perhaps some more current available on the power transformer. Anyway, with all the tubes in, a load connected, and after settling down after turn on, I measure a B+ of about 436-438 volts. That is rather high compared to the published 400 volts. In any event, it does sound good. I know that Morrison purposely runs the tubes hot and out of spec. I want to run it the way he planned rather than return everything to a "normal" operation. Do I need to make some adjustments to make it run according to his design? What should I do? Any suggestions would be appreciated. Best, David |
