I have accumulated quite a few 7 & 10" reel tapes over the last 40 years. I remember to have used a four speed tape recorder (7",3-3/4",1-7/8" and 15/16" speed).In order to paly those tapes and convert them to casette tapes and/or CDS, are there any tape-recorders new or old available on the market? I am not sure that the original tape recorder was manufactured by B&O. Any advice?
