Hi everyone, I'm new around these parts and I have a project I'd like some help with.
I am building an effect unit using a reel to reel tape machine. It is a take on an effect created by Ken Townsend for the Beatles called ADT. It used a oscillator to control the speed of the tape machine. It had one large knob to manually vary the speed by small amounts to create the effect. I want to reproduce this effect but I want to be able to set the initial speed manually and have an LFO control the small variations in speed. The motor is a four pole induction type, 100VAC. The motor currently moves tape at 7.5 inches per second. I need to be able to set the speed to between 24 and 118 ips and then vary it with the LFO at a rate of say 1hz to more extreme setting of 100hz or more to vary the IPS by milliseconds. If I can clarify anything any more please ask. I have electronics experience, just not in this area.
Many thanks in advance,
Zowno
