[Pine Marten]

So it looks like ther are 4 3v bulbs! The two for the vu lamps in series and the two for counter and tape compartment in series, if I'm reading the diagrams correctly. It looks like the ones on the meters should unclip and be easy to swap for leds, with plenty of room for a dropper resistor too. Leds, Din plugs etc all here now so another go at the weekend! My meter board is a green one!
