GTO, I need to know a bit more. The type of amp you have? How old is the amp? It sounds like it could be a few things as you have different symptoms. On the noise all the time - could be a preamp tube - does this happen if you lift the ground with a lift? Does it happen the same in all places, as you may have bad AC? The noise from the back of the amp is some sort of vibration of a component or microphonics in possibly an output tube. These would both happen at certain frequencies. In combo amps this is more of a common occurance. If you have a Mesa product, this is quite common as they use self tapping sheet metal screws to hold everything, even heavy items such as transformers, and these amps need to be "torqued down" at least a few times a year with regular use. Regards, It's a Traynor YCV80 (2x12). I haven't had it for very long, just a few months. If it's the preamp or power amp tubes, what should I look for? How should the tubes be seated? I'm a little in the dark here. I bought the amp mail order after I heard a friend's YCV40 and have been very pleased with the tone. Unfortunately, these problems have popped up recently. I've been in contact with Yorkville and they said to send it to them. I hate to tell ya but it's gonna be expensive just to send the thing to and fro and I'm concerned that it'll come back with a note saying that they couldn't find anything wrong with it. I was wondering if there's something that I could do to rectify the situation myself or locally, I live in the Cincinnati,OH area. I'm a novice at amps but have worked with electronics for a while now. Any suggestions? Thanks for responding BTW.

Hey Myles! When you get a chance, I'm noticing a buzzing noise through my amp when I'm not touching the strings on my guitar. It's actually not that loud but it is noticeable. What could this be? It's happening with all of my guitars, single coil(s) and humbucker(s). Also, what could be a jangly noise coming from the back of the amp that only is audible as certain notes are played at about half volume? Thanks for your time and the info

Thanks for the reply Myles. The "still around" comment was an inadvertant leftover paste from the HC forum, please don't be offended. Thanks for the info James and Myles, both of you hit the nail on the head.

James, Please butt in any time. Great info, you cleared up the issue that I was most concerned about, when to switch to standby at power-on. Thanks!

Myles, great info! I hope you're still around. Could you go over the basics of using the "Standby" switch, or point us to a link. I believe this is a much overlooked issue with tube amps and improper use can cause tubes to wear out prematurely. Also, I'm sure that I'll learn something too, as I'm certainly no expert. Thanks.
