I did not swap Monoblocks, as I had just started my trouble shooting when I returned from my trip... And the problem seemed to start happening more often, which made it easier to find.
Not sure how many hours I had on my Tubes... They were used when I put them about 8-10 years ago.... 1930s Vintage RCA UX-245 Globes --- About 90 years Old! --- Amazing that they lasted this long.
Tubes last a lot longer than I thought they would.

Yes, this will take some time to troubleshoot, as it is very intermittent...... - Cut-Throat 06:42:47 07/21/19 ( 0)
