Default Re: AVO 163 amp board ~ transformers

That seems like the figures I got on the few Philips/NXP that I tested, but I also got a few that was way higher, almost double that figure.

It seems like the only way to check the amplifier is to hook it up to an oscillator with a variable output that can be varied down to the mV range and test it, using a DMM on the µA range across a 1500 Ohm resistor in place of the meter outputs to see how it behaves over that range.

Checking all components might be necessary too.
