Marshall DSL100HR

I have to start off with stating that this is my first tube amp (although i have played other tube amps before). That being said i have to say that i really really like this amp. Its amazingly "fat" in the low end even with a single v30 speaker in 50W mode, although i feel that it does need a boost even in the od 2 setting to get all the agressivenes out of the amp. The clean is nice, and going with the crunch mode plus an BOSS SD1 it goes towards a nice JCM 800 type of sound. Only con for me is that its very big and chunky, kind of getting why people love the EVH 5150 50W amp being smaller than most full heads. In conclusion, great amp, great sound, a little big and chunky to move around when you have to, and the built in reverb leaves a LOT to be desired, but then again you have a free reverb built in... so yeah whatever!

When the amp arrived, i decided to take it to my technician right away to inspect it, change tubes etc, like i always do with new amps.
I definitely wanted to try it before it went to the technician, and it sounded great right away, but after half an hour i noticed it was getting too hot, anyway, i tried different channels and when i pressed the master button one of the tubes blow off, i heard a loud pop and i immediately turned the amp off.
Took the amp to the technician, and the first thing he did, he measured the voltage in tubes.
So ,left side was 80 mV, and the right side was 40 mV (while the tubes are marked at 51 mV, obviously they are not) and that's why they were so hot.
Then he realized that the tube sockets are wobbly.

To shorten the story , he replaced all tube sockets and all the tubes (puts in a Mesa Spax ECC83 in preamp and original Marshall EL34 in power amp), did the bias thing, puts all the tubes exactly to 50 mV, and now this DSL kicks ass.
Sounds great, feels great, and it looks sexy :D

I recommend that whenever you buy a new amplifier take it away to your technician or someone who knows what he's doing, to be sure what is going on
