I have acquired a few old 78rpm records. Now, i have a record player that can play at the rate of 78, but it seems there is a problem with a few of the records. The record just sounds sped up, just by a bit, but it makes the song sound high-pitched, and annoying. I am wondering if this is a fault of the record, or just that some records are too fast for modern players?

I also have another question concerning records. I very recently got another record, which unfortunately has been cracked (The label is Coral, which seems to create VERY easily brake-able records). The crack doesn't affect play much, except for the occasional "pop". Now, my question is, at the beginning of the song (this will be difficult to explain), the music starts, then when the singers come in, their voices are contorted in a strange echo-y, and fuzzy way, only for the one beginning line, then the rest of the song is normal. My guess would be dirt, or something similar causing this, for i have yet to acquire a cleaner. But i just wanted to know if it was (again) the record itself.

I hope all that made sense, i try to explain best i can. Any help would be greatly appreciated. :]
