So there’s a possibility of adding a couple of play heads as well and get them to mix at different levels? Also the board you used does it only have the 7668 chip or the output from that 7668 run into some other chip like a BBE chip since I’m trying to find this board on eBay and there are variants with just the 7668 board and others that have two chips including the 7668….BTW thanks for your advice on the other video to come and check this one out this is really a great non invasive way of creating a tape echo without really breaking anything on your reel to reel!!
Thank you! Tape heads produce quite a weak signal. While it certainly CAN be amplified by a decent microphone amplifier, even a simpler dedicated tape head amplifier works better. If you want to use just an opamp that works fine, I tried with the recovery circuitry for my spring reverb and that sort of amplification did OK too. Still, for this I used a Ta7668 Tape Drive Preamplifier Amplifier Tape board. They are all over the Internet.
@@jacobsteel Thanks! I've done something similar with a $2 LM386 chip amp. But not knowing what I am doing, I wasn't sure whether there is something more needed to boost tape head signal beyond just making it louder. I've only experimented with cassette tapes, your video makes me want to find a reel to reel. Thanks again.
@@adehanft - reel-to-reel is easier to work with. The first tape delays I made I used the amps from old tape decks... This one has an old broken Walkman as amplifier for the extra head: ruclips.net/video/-xT16pdS3Ao/видео.html This one just flips one of the two rec/play switches and uses L for record and R for playback: ruclips.net/video/OYjC2h2sVaE/видео.html Great fun building tape echos! Best of luck! :)

Very cool. Where did the tape head amplifier come from? Wondering the difference between that and a normal amplifier.
Thank you!
