I have decided to send them back to the dealer so that he in turn can
deliver them to Quad for a complete check-up.



They should be repaneled.
If you bought them with a full warranty, the dealer should pay for the
costs, which would amount about $1000 per panel.


My queries really are, first of all, why is my friends Quad amplifier
quite cold in operation and standby, I understand its an older and
smaller powered 303, (or some such number). Quad tell me its normal for
the 909 to be hot, but how hot, as mine is almost untouchable when under
power and I can smell the new paint on it.



That is simply too hot for any amp.
I have no experience with the 909, but if that amp is designed along
the lines of the 606, 405 and 303, it is biased in class AB and as
such, shouldn't get too hot under normal conditions.

Try the 909 with your friend's 63s and see if it gets too hot, too.
If so, there's probably something wrong with it.

A lot to digest and thank you for the above. I will be putting back my
old B and W's today and then will be better able to test the temperature
of the amp, thank you again.
