50030 ETH Overvolt Relay HOVR board April 2011
This is the board mounting the ETH overvolt relay (HOVR) & resistors Z23, Z24 & Z69, which is seen in April 2011 shortly after it had been test mounted in 50030's electrical cubicle, but had not yet been properly fitted and wired in. The components on the board have all been cleaned, checked, tested and overhauled as appropriate.
