Has anyone got the circuit diagram of the printed circuit board in the
Potterton Profile Control Unit?
In particular can anyone tell me the resistance value of the resistor
R15? The painted bands have gone on the one in my unit.

There is a company that refurbishes these units at reasonable cost
(with VAT and post they are still under 1/2 what you would give at
spares shop fro anew one), they also come with a 12 month guarantee.

The owner will probably be along soon to tell just how much. The only way
I could tell you is by dismantling my working spare unit from my store
room.
