Cassette decks offer a ton of fun and a real blast from the past user experience, but there are a few things to consider before you go crazy.
Cassette decks are amongst the most complex of hi-fi gear and generally require the most maintenance due to their electro-mechanical nature. Think of the VCR you used to own, and you’ll not be far away.
This maintenance is regular and periodic, with some necessary every 10 hours or so. It’s also specialised, requiring special tools, lubricants, demagnetisers, calibration/test tapes and more. The work can be time-consuming and technical, and much of it is way beyond most owners. So, the catch-22 with cassette decks is that as fun as they are, they can be costly to maintain.
Whatever, I have several cassette decks and I love playing tapes. It really takes me back and a good three-head dual capstan machine like my Pioneer CT-A9X will sound excellent. Just remember compact cassette as it is correctly called is not a true hi-fi medium and was never intended to be. Better decks with good tapes can sound excellent, but it’s more about the experience: warmth, VU meters, spinning reels and tactile interaction with these wonderful whirring machines.
If you want a cassette deck, look for a better, three head, dual capstan deck, from one of the bigger players like AKAI, Kenwood, Pioneer, Revox, Sony, TEAC, Technics, Yamaha and Nakamichi. Better decks cost more and are worth more, so the inevitable maintenance doesn’t feel so painful.
Full ‘mechanism out’ services have to be done periodically and can take many hours. Many more hours can be spent on calibration. Most decks need major work at this age and the better decks are still very serviceable, but heads, pinch rollers and some other parts may be impossible to obtain, so choose carefully. If in doubt, get good advice from someone who actually works on these wonderful old machines, and consider a specialist forum like TapeHeads.
