I'm sorry if I shouldn't ask this question here since it is a ukulele forum and not a vintage amp forum. I thought I would tho since there are some on here that know a lot about guitars and amps along with ukes. I posted this thread in is part of the forum because I didn't think it would be seen by the ones I wanted to see it if it was posted in the guitar area.
I have a 1959 Gibson Explorer GA-18T. The tolex is yellowish tweed looking not actual tweed but looks like it. It is a tolex or vinyl covered and it is original.
The covering is in great condition except the bottom of the amp. It has a black and brownish color mold on about 3/4 of the bottom. I tried Comet and hot water several times to remove the black and it hasn't removed it and I scrubbed pretty hard too. I don't know if some of you guys had experienced this and knew of what may work to get this off. It's really a bummer because the rest of the amp is in excellent shape and all original.
One other problem question also if you don't mind. There is a part of the tolex on the bottom also that is raised maybe a little less then a 1/4 of the surface where it is loose from coming unglued and I'm not sure how to repair it. There are no tears in the tolex so that I could put some kind of adhesive or glue under it to get it to stick back to the cabinet. This was already loose and didn't happen from my trying to clean with the comet and water. I'm guessing it probably happened at the same time that it got the mold from being in a damp place. I was wondering if maybe i tried an iron on low with a rag under it and see if that would maybe help it adhere back like its supposed too or if the tolex was going to have to be cut to add glue under it to repair that part of it. I was wanting to avoid doing that if possible. The older gentleman said he bought it new when he was 15 years old when I bought it from him a couple of years ago and said it spent many years stored in a garage. It even has the original tubes made by RCA for Gibson in it. I took the original gray 59 Jenson PR-10 speaker with the big bell out and replaced it with a Weber Alnico because I had always heard you should do this when buying an old amp like that to avoid blowing the original. I have it put up safe in the closet in the box the Jensen came in so it would stay safe.
I can upload some pictures tomorrow if you want to see the mold and the raised tolex.
I'm sorry to have made such a long thread for these questions I have about it but I just wanted to give all the info I could so someone wouldn't have to waste their time in aking questions back about what I tried or how it happened and so forth. I didn't ask this question on another forum because it seems like a lot of ukelele luthiers and players with experience on this forum don't seem to mind helping us players when we have a problem that we need help with. I've asked questions about guitar related things on other forums such as Gibson and Les Paul and the tele forums and no one seems to ever want to help or don't have suggestions for me and I'm guessing it's probably because I'm not a frequent flyer on them. Most of my time is spent on this forum.
I hope someone can help me with these problems and again my appoligies for asking about a non uke related problem that I need some professional help with.
Thank you all in advance for any input you may have that would help me.
