'morning engineers,
I woke up with the insane idea of making a tape delay and, as unemployment stands firm, is the perfect time to build something cool.
(my girl works so don't send me money please, just infos!!)
I've found this block schematic of the Roland space echo which is very helpfull to this project, but contains 2 modules in particular that i would like to understand, the MOTOR DRIVER and the BIAS OSCILLATOR+BIAS TRAP.
Both are all discrete design on the original, and i wonder if there is a way to simplify them with ICs, the same i want to do with the whole machine..
Second, the mechanics.
the main question is: do i need just one point on the tape loop where the motor spins or i need that both the capstain and one reel are coupled to the motor?
last thing: which heads are suitable for that job? and who sells them?
Any information or link on the subject is really welcome,
and thanks in advance to everyone who shares his knowledge on this forum,
you are the best!
if somebody is interested in this project, plesase keep in touch around here.
