Hi Håkan,

Thanks for the response and link - much appreciated. You are absolutely correct but.before replacing the IC I removed and cleaned the IC Socket (with switch cleaner). The original IC was then re-inserted with the same results. The fault only cleared after replacing the IC I obtained from a cannibalised Tek 465B. Note that I have also cleaned and re-inserted most of the transistors and IC's (sockets - took a long time!) due to possible poor contact, plus cleaned all the switches.
