Thanks to all who replied to my query. I have found it is the FET which is
faulty, have a number of spares available. Haven't been able to get to it
yet, my young brother has been visiting, but will start on it this weekend.

Pwr supply is similar in all: Tektronix 2213/2215/2213A. bama.sbc.edu
as a starting point for free download.

check postings of Jim Yanik and others in sci.electronics.* for this
type of fault.

This type of Tektronix scope has an SMPS with a primary pre-req
circuit. Faults, repair hints and corrections are often described in
e.g. sci.electronics.repair and similar.

Most often: TL597 IC blown, FET blown, fast recorvery diode blown.
