rosa Posted March 16, 2020 Report Share Posted March 16, 2020 Hi, I have a Teac r1000, which is 4 track 2 channels, and have restored the transport to good working condition. My plan is to use it as a delay, so am searching for full track mono heads for it. If I do find compatible heads, would the circuit in the preamp section of the deck for the three heads most likely need modifications, or could I simply use one of the 2 channels to work with the mono head by making the necessary calibration adjustments? Thanks, Rodrigo Quote Link to comment Share on other sites More sharing options...

Thanks, Rodrigo Nowhere is the phrase, "It depends" more appropriate -- starting with the specs and operating parameters of both the specific heads and of the preamp circuits.

Rick Reineke Posted March 17, 2020 Report Share Posted March 17, 2020 If the goal is for a slap-back echo, I would not worry about the head stack. Vintage Space Echos and such never did have a primo response, but most everyone loves the sound. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted March 17, 2020 Report Share Posted March 17, 2020 My very fave echo devices: the Binson "Echo-Rec" and the original Klempt "Echolette" were really lo-fi devices, even for the times they were originally sold in. That's part of their charm, and why people still use them. I agree--if your tape deck is operational just use it as-is, a wider track won't make any real difference in the sound if you are using the same electronics and transport.

rosa Posted March 17, 2020 Author Report Share Posted March 17, 2020 Glad we reached a consensus. Its does sound nice already when I ran it with a synth, and I still have work to do in the preamp section . Also curious about controlling the capstan motor speed, I believe its DC .

Philip Perkins Posted March 18, 2020 Report Share Posted March 18, 2020 You need a service manual for your deck. Sometimes they come up on Ebay. If the machine did not come from the factory with a varispeed control it will be kind of complex to make this work, at some danger to your motor. We recently looked into this for some fairly expensive vintage hifi decks, and concluded that it wasn't really possible. Quote Link to comment Share on other sites More sharing options...
