No worries, schematics can be a bit daunting at times but remember that they can be broken down into individual blocks and those blocks can be broken down into sub circuits that are easier to understand.

If in doubt, always go back to first principles, AC, DC, voltage, resistance, capacitance, inductance, impedance etc. learn the basics of them and they will stand you in good.

My PM isn't enabled anymore, that's because I am unlikely to give or want personal info via it.

I used to give fault finding tips to individuals via PM but don't anymore as I now feel it's better to discuss such things in an open forum for the benefit of other members and future members.
