Hi, and welcome to something I hope is helpful to you — some simple testing of audio plugins which you can use for comparing, or just to find out more about each one.
The Joys of Analog Tape:
Calibrate it every day. Keep the tapes in a controlled environment. Push the signal so you get less noise, but not so hard that it distorts. Clean the heads and capstan. Be careful you don’t stretch the tape rewinding. Keep a log of how many punch-ins and re-records you have done. Test the motor and transports.
