Cassette tapes and old audio (Kingswood BS15)

Hi all, one of my passions is old audio items, I enjoy collecting and repairing things such as radio cassette recorders, ghetto blasters, walkmans, reel to reel etc. also I regularly play and record to cassette so if you have any old tapes you no longer want, particular recordable ones, I would definitely be interested. As mentioned, with the machines it doesn’t matter if working or not as I enjoy repairing things. Thanks, Tim
