my name is Rene, from 1985 to 1999 I used to repair in and out of warranty cassette decks and walkmans for Kenwood, Yamaha , Pioneer, Sanyo and other brands and with the current increasing interest in analog audio, and cassette decks in particular, I started this channel to share tips and tricks that I have picked up over the years.
I will mostly do 'end-to-end' video's about repairing, servicing and adjusting the deck from beginning to end with a lot of talking , showing , tips etc and very little editing.
If you have any questions or particular video's you would like to see just reach out and maybe I can assist ?
