We have a White model 1500 4 string machine. It was purchased about 13 years ago and has been used maybe 5 times. It worked great when we first got it, my wife used it for her wedding dress, and then put it into storage. After a year of storage, she has not been able to get the tension to be stable. She has used maybe 5 times since and gets tired of the tension going off, and puts it back in the box. I looked at it, and I can adjust it for a perfect stitch, but after a minute it goes off. Readjust, a few minutes later it's off and needs to be tweaked. It doesn't just go off a little - it goes from right on to way off and ruins the stich of whatever is being worked on. On a long run, you can see it go on and off, on and off. About this time she is going, uh huh, didn't believe me, did you lol. Does this sound familiar to anyone?
We had a nice Elna, but we took it to the wrong shop, and they charged us $100+ and messed it up worse then it was to start, and the machine ended up going in the trash because it just wasn't worth spending more money on it. Because of this experience, I'm really leary of paying someone $100+ to service this machine since because I've been burned once and am seriously considering chucking this machine and just getting a new one.
Any suggestions, other then throw it in the trash and get another one? Is there any hope for this old machine?
