im not sending it back, i have a guy that lives near me that works on electronics for a living, and he said it was a simple fix. so he is doin it for me.

Just wondering if anyone knew the Mesa tube bias for EL34's. and Their idle current flow (in milliamps) . if anyone could help me out with this, it would be excellent.

it turns out it was a screen resistor, i think it blew before i got the amp. but man that thing melted down pretty good. i cant wait to hear the amp with full power.

I recently noticed on my 2003 Dual Rectifier solo head that all the tubes were gloing on the amp when in standby, but when i switched standby off only 3 of the power tubes had that blue glow from the voltage hitting them. I thought the 1st tube was dead because of this. so i went and bought a...

hey thanks you guys. The amp still works, i just wanted to know if any damage had been caused. im still geting buzz but thats because of my ground in the guitar and i cant seem to fix it,

the manual says that the amp can run safely at 4, 8, 16 ohm loads but running at 2 will damage the output transformer. so is runing 2 8 ohm jacks to 2 8 ohm speaker inputs is 16 ohm? but this is not safe, or is it ok?

just wondering what happens when your output tranformer is damaged? does it just break the signal or what? just asking because one of my friends tried out my head and he might have plugged in from the 2-8 ohm jacks into 2-8 ohm stereo cab. and if he did, it was only like that for about 10...

when i turn the output volume up to rehersal volume i get popping sounds in every channel, it's only noticeabel when im not playing. this started happening a few weeks ago, but now the popping has become faster and more noticeable. Is it time for new preamp tubes? by the way its a 2003 dual...

the gate is infront of the amp, and i have tried two different power supplies. i have also tried different cables but there probably not high quality. Guitar > gate > Dual recitifier > 412 cab i just seem to get more hiss when i have the gate in the chain, than i do with out it. it might...

mine always pops the first time i hit channel 2, and yes its very annoying. but i always go through the switches before i start playin.

I have a dbx 266xl gate/compresser that i use to gate the guitar. but when i have it in my chain more hum comes out of the dirty channel, i have tried numerous things buy i cant seem to get it to stop humming. its fine at low volumes but it will be very annoying at a gig because when the...

I just have to say, every time i go and play this amp it sounds better and better IMO. I'm sooo in love with this head. now i just need a new cab. mine will do for now :D

i have a 16 ohm 412 and it sounds monstrous, but never played through an 8, my guess is it will be alot louder obviously.

im just afraid that if i turn the channel volume down, i wont get the same sound with the master volume up. Does this make a difference?

ok thanks guys. i have also hear if you mess around with your loop settings (send level return level) it will help boost the volume.

I just recieved my Head a few weeks ago. I had my first gig with it two nights ago and man! i am sooo impressed with this thing. it was definetly the sound i was looking for. the only problem i have encountered is the matching the volumes the clean channel is maxed and my dirty channel is on...
