I played again with the DT50/HD500 4CM in LVM and love the control I have with it. I played yesterday for about 40 min. and today for about 1 1/4 hours.
Just 'cause I thought of it ran the infrared thermometer around the back of the chassis and the front to see what range I had at an ambient temp of 76 F and 55% humidity, lol. Pointing the thermometer at the power tube section I got a high of 156 F and it cooled quickly to 136 F. Everywhere else around the chassis along the metal face front and back was 100 F. The transformer areas where 100 F. I don't have a fan blowing on it since it's relatively cool in here. This test was done about 3 minutes after I powered the amp down.

That would be awesome, Brazzy! I'm going to try to wedge an oven thermometer to it somehow, though I am not sure it'll work. I did fire up the old Dual Showman Reverb, and it did get hot, but not as hot. Plus it has maybe 20 tubes in it as opposed to the DT50's four.
I measured the temp of my DT50 Head by just holding a Cat No 22-171 Radio Shack Waterproof Pocket IR Thermometer as close to the screen in three spots. In the middle were the tubes are measured approx. 170 degrees F, to the left and right were around 90 degrees F. I would estimate the glass is around 200 degrees. Remember, this is an estimate and the testing was done indoors in a low humidity room at approx 78 degrees F.
I've used the Global EQ to cut the lows a little and accent the mids and highs a bit. I like Global EQ and it sure works good. I'm not using an EQ in the chain when using the DT50 live but when I record with the computer using HD500 USB I usually use and EQ in the chain for high gain patches.
Seems like all models even the full amp models and effects sound better and respond to tweaking better using the 4CM or it's just me. So far I'm loving the 4CM in both 25w mode and 50w mode. I've got to try micing the cab on this one day when it's quiet in here and try the Direct Cab Simulated Out too.
A total of about 3 hours of good playing time so far.
4 cable method. Does it really work?
Added another 3 hours of playing total now is 6 hrs, in 45 min. sessions.
Used the DT50HD for another 1 hrs. 30 min. 6/24/2015 with DT Edit
Updated total = 8 hrs. 15 min.
Amp B" doesn't seem to work with my HD500
Add another 45 min. = Total 9 hrs.
Add another 1 hr. = Total 10 hrs.
Damage to my rig using this set up?
