From the Quad 33 Service Manual......" The DC supply provided on pin 4 of
the output plug, derived from diode MR503, is used only as switching supply
for special installations. Its regulation is poor and it is nominally 7-8
volts at 1 milliamp maximum, intermittent rating."

It was discontinued at S/N 80,000.


Excellent! Thanks very much. Looks like its certainly no good for a
headphone amp then - never mind!
(This is S/N 57751 by the way, getting on a bit - like me... :-) )
