Phono 3S Relay board revision and rebuild question

[David Roberts]

Having recently acquired a Phono 3S, with relay ‘issues’ (the repair of which necessitated the removal of the relay board), I am planning to revise the component placement before refitting the board, which should help to facilitate future repairs if required. This idea has been briefly discussed on a previous occasion on this forum, but I wanted to make sure that I have got the procedure right, and would like to hear from any member who may have already undertaken this mod’.

In order to preserve the correct pin connections, the relay must be reorientated, and fitted upside down in its new position on the visible side of the board. Am I correct in thinking that the two diodes need to be turned upside down as well, and does this also mean that the relay power supply wires need to be changed over (so that the switching is changed to the + line)?

Many thanks,

David
