I'm 19 years of age however I've been doing cassette repair for 4 years at this point. I'm a huge enthusiast - as cassettes are my main way of listening to music. I do a lot of repairs, mostly walkman and am here to ask questions and share the hobby. My main deck is the Sony-K909ES, my main portable is a modded WM-EX9 with brass flywheels and my favorite tape ever made is the maxell XLII-S with the heavy shell.
Welcome to the forum! Doing repairs is 1/2 the fun and good for your brain. It's a great hobby if you like gadgets and the hunt for good cassette music. Maxell's were my tape of choice in the 80's, they always had a good price on 2 for 1's and they always came out nice.
