Here are some pictures.

I think this was built as a small numbers of units as it uses a large number of RS Components parts, and the mechanical build uses drilled holes rather than punched.

The power transformer is not in good shape, but the RM3 lacks the stinkyness one usually associates with a selenium meltdown.

I'm a little way through reverse engineering it, the physical layout drawing is attached.

So I need to repair or renew the transformer and can anyone tell me anything about the resistors?
