As some of you know from reading my posts,I just bought a porta one. I really like this deck for it's portable nature and I'm impressed with it's quality sound. It kinda broke after 2 hours of use. It was finicky right from the start and went down hill from there. tape play/record heads would not retract nor would it FF/RR, also made a straining sound.Well I took it apart,sprayed some WD40 into the gobledegook of the mechanics and Presto,It has been working perfectly for many hours of on and off since 4 pm yesterday.I was messing with it till 2 am. I don't know the history of the unit but the dealer who sold it said for at least 6 months it sat on a shelf,I hope the fix lasts,At least it's not too big of a deal to open it up. What amazing stuff.
