A few years back l bought an Akai GX-220D three motor, 4 track three head auto-reverse on impulse from eBay £79
Recapped and with no additional maintenance needed it is now in good shape. Bought 12 new and some used Agfa 7” tapes from one guy for £30 + P&P again from eBay. Soon up and running for £200 all in. I was so impressed (only had a Grundig mono R to R in my teens) I spent a little more on about 10 pre-recorded 3 3/4 and 7 1/2 ips tapes for good measure.
l can’t put my finger on it but 7 1/2 ips (no Dolby) there’s just something about that sound. Yes it’s of novelty value, l do not play around with it often, but it adds some razzamataz to the music.
