I never looked at the tubes while running the amp but it actually runs very cool.
On the other hand if it wasn't correctly tuned as, I suspect it wasn't, like you say the tubes were most likely taking a beating.
There's on more thing I'm going to do and that's turn the driver output up a bit from under 11/2 to 2 watts dead key.
I always wondered what if any difference a 2 watt dk will make if any at all.
Now I've 10 replacement 6lq6's and doubt I need them.
I guess It'll be a long time before I worry about having to purchase any more.
I paid about $10ea. for them. It's amazing that the Sylvania's in there are stamped with the d&a mark. If there not original they were probably purchased from d&a early on and replaced by original owner of the amp. I'm not sure if one could purchase replacements from d&a but if so they were probably no more than$7 ea. At 800 watts pep with about 11/2 dk and 20 pep I'm guessing the Tubes are good. 800 seems to be the consensus as far as output for the phantom.
I would definitely suggest anyone owning a phantom no matter which one check the twin peak situation. Re tuning the amp sure made a difference and the other good thing to come out of it was it's most likely tuned properly for the first time since I've owned it. Thanks.73 p.s. I'm still very tempted to drop the replacements i bought in. Good damn!! I really am a chicken bander. I'm getting 800 out of it and even though I know a couple of hundred more isn't going to make a difference on the other end I wanna see the wm 1 hit a 1000. I jest!!
