Moderators justcrash Posted March 11, 2009 Moderators Share Posted March 11, 2009 A half hour bump and 15 minute bump at 6:30 AM and you're indignant no one has responded yet? Regardless, probably a bad tube or a fuse on the way out. I would take it to a shop. Link to comment Share on other sites More sharing options...

Members JerryP Posted March 11, 2009 Members Share Posted March 11, 2009 My first guess is bad preamp tube. Take them out of them amp and tap them while holding them near your ear. If you hear one that rings like a snare drum it's probably bad. Jerry Link to comment Share on other sites More sharing options...
Members AL30 Posted March 11, 2009 Members Share Posted March 11, 2009 Always try the tubes first. They are the easiest part of the amp to access and cause a lot of amp "problems". You didn't really explain your problem very well but from the sounds of it you are getting some ghosting. This may be a capacitor problem. If the amp is over 20 years old it's time for some new caps. Most caps will give you 10 -15 years (according to the white papers). If you're planning on playing any older amp on a regular basis it's in your best interest to get a cap job. If you're afraid of the "vintage" aspect then save the caps - just in case you sell it down the road and someone wants an amp that doesn't work properly or wants to blow a transformer.

Members Jcm800_6550 Posted March 11, 2009 Author Members Share Posted March 11, 2009 lol I'm not gonna sell it i just tried out a mesa dual rec 2 ch and too much tweaking to be done and even with good setting i didn't like it, however i didn't do any boosting with an od pedal so maybe that played a role but im satisfied with my 800 especially when i get that new cab that i tried out , im just getting agitated with all of the repairs and $ I'm putting into it, but i guess that just comes with good tone out of a 28 year old amp, 28 years old danm...

Wow! How much stuff did you have to have done so far? I always thought that a JCM 800 (2203 or 2204) would be more reliable than a lot of other amps due to it's simplicity. I'm probably wrong though..... Link to comment Share on other sites More sharing options...
