Question from another group. How do you identify which Mark the amp is
if the identification plate is unreadable?

Ideally, by being able to trace the circuit, etc. :-)

However as a start, does it have adjustment pots for the bias? And are any
numbers on the transformers readable?

BTW There is a 'radford' email list if the enquirer has a serious interest.
That also allows access to diagrams, etc - provided you are willing to
agree the 'terms' laid out by the webhosts.

Slainte,

Jim
