    it's entirely possible that it's your problem.... since you obviously have a 2 prong pug on the beast... just for shits and grins reverse the plug to see if it improves.... otherwise get a tech to install a good cord...

    i try that thx, the thing sounds great but there is a lot of noise in the signal ive tried diffrent guitars and that dosent seem to help. does anyone think the tubes might be the prob , they dont look so good and 2 of them have been replaced with peveay tubes(that cant be good)

    i think the peavey tubes are rebranded sovtek so they may not be too bad... best thing i can suggest is take it to the best tech you can find in your area... all techs are not created equall and if you want it done right find out who the top plyers in your area go to and go to them... this is especially important with vintage devices...

    All of the above. Definitely have someone install a properly grounded cord.

    An amp that old could have other minor problems that will exist even after adding a cord. A good amp tech will inspect and replace capacitors, if needed. Those can cause a lot of noise. He'll clean the pots and jacks properly. He'll test all the tubes to see if they are still strong. He'll check voltages at points to make sure other components are within spec.

    A GOOD tech will give you an estimate, and communicate with you if he finds a more costly problem BEFORE he repairs that problem. He may also give you a choice of lower-cost tube or other parts replacement that will get by, or higher quality, pricier parts that may make it sing more sweetly.

    He may even ask you about tonal preferences, and suggest small, inexpensive tweaks to get "more grind", "more clean", "more highs", "more smooth"...whatever. You should let him know what you like and DON'T like about the amp in its present state...other than the obvious.

    Some guys pride themselves with getting an amp to induce an ear-orgasm, and may actually work longer than they have charged you in hourly rates just to satisfy themselves in meeting the challenge. I know one of those.

    Some guys will charge you EXTRA time than they have worked just to install the cord, change a cap and say "here ya works". He may have only worked for an hour and 1 minute on it, but want to charge you two or more hours...just to make it worth his while.

    I've known both. Listen to other musicians' advice. They know who's a jerk, or not.

    Those old Gibsons can be sweet-sounding amps. Definitely worth doing right.

    Absolutely take it to a good technician! Many guys have gotten killed with the problem that you described! DON'T SCREW AROUND! YOU COULD GET KILLED!
