Thank you. Found a last few spare 24A tubes and began swapping. I did find one that so far in 2hrs of operation has not popped, dropped in volume, or faded. The one thing I do notice is when initially powered on volume is high then settles. Not noticeable if at lowest setting when powered up and wait until set warms up. If you have volume at half setting and power up it is really noticeable.
