Original Mk2 Phono Mother Board - with replacement relays Side view. New board fully rebuilt. Old board - Empty! There are just 2 (carbon film) resistors on this board, a 33Ω and a 5.6Ω - the 5.6Ω had drifted to 7.4Ω so it was replaced, along with the 33Ω for completeness. The new board is beautiful, a top quality replacement designed by AK's own Ronito6. This is particularly for anyone with a Mk1 board, which has a bewildering array of factory modifications to make it stable. But also for anyone with a Mk2 board wishing to rationalise the mounting of the much needed replacement signal relays which have a different PCB 'footprint' compared to the old unreliable relays. Ron was also significantly helped by AK member Willy6 with installation testing & tweaks and ordering boards from the US based PCB fabricator. The topside silk screening has been much enhanced by indicating the colours of the connecting wiring, making it a very easy job to wire back into the unit.
