I've started to notice some wow and flutter with one of my Tascam 244 decks - the most recent one which I modified for Type 1. The frequency response is still outstanding, but I'm noticing w&f at the sort of level you get with a standard cassette deck, which spoils acoustic guitar recordings, which were sounding great. Oddly, it sounds ok on headphones but over some good speakers it just isn't right. I replaced the capstan belt and head control belts when I bought it this time last year but it still has the original pinch roller. I've cleaned this thoroughly and it is not in any way "sticky" like previous 244 rollers I've replaced - but could this be the problem? I just want to make sure before taking everything apart again - I'm concerned about losing that little spring clip on the roller and want to make sure If there is something else I'm missing! Any help appreciated!
