Nice one Chris, good to have another join the colour club, slowly but surely we convert you all
For you it had to be a PYE didn't it
The full PYE service manual for this chassis can be found in the data library. Not forgetting the additional and superb decoder diagnostics guide, with this chassis you're going to need it
Also don't forget all the stock faults for early colour are also available from the main site top menu "stock faults", including PYE. Then there's Les Lawry-Johns article called "Hot Pyes" which is available from the menu "Service" | "CTV service tips".
Here's what it looked like new in 1972....... you want to keep any eye out for a stand now, unless it came with one.
