Little Reel-to-Reel Tape Recorder! Dokorder PT-4K

For about 13 years I searched. I placed my bids on eBay. The year was around 2008 or so. Auction canceled. Yeah. Fast forward. The year was 2013 or 2014. I was with a girl I liked, but never got to be with due to her friend-zoning me. Whilst with her, another of this model recorder was on eBay, and the auction was ending. I bid, but was outbid. Dang. Finally, this year, 2021, I find this machine on eBay again, as a Buy it Now. I finally got one!!!


This six transistor tape recorder is very nice. Its bias will be revealed in the video. This unit is from 1962, as I found an article online about it in a British magezine. It was early enough in 1962 that this recorder might even date to 1961.


This unit works on original parts, but I modified it so only the motor would turn off when the remote switch was turned off. I also installed NiCd cells, and built a battery charger for the recorder.


This two speed recorder is manual level control only. Frequency response is 200Hz to 7kHz. Its cousin, the PT-4H, uses manual rewind and has no meter. Its response only goes to 5kHz.


Music presented in the video is NOT BY ME, DUH!!!
