Re: Need an Isolation Transformer for CTX-S (Philips 14CT2006)
The TDA2577 data sheet shows that connecting pin 13 to 12v via a 12k resistor changes the time constant for use with a VCR. Therefore try connecting D8 to pin 13 via a 12k resistor.
If you are going to use it with a VCR I'd keep the audio input but delete all the circuit associated with the audio output ( IC2b, IC2c and IC2d and the associated components) I'll post a modified circuit later.
