And of course I’ve spoke too soon, the HT has now started to make that distinct high pitched whine that it does. Fortunately I have a spare analogue board, so let’s hope the pinout is the same.

Speaking to soon is something we all need to get out of the habit of!

@rubber_jonnie especially when your spare analogue board is slightly different annoyingly. It’s got a different Ht coil. Might have another somewhere, fingers crossed.

Is it from the same machine or something different?

Same machine but the analog board must be a different revision.

Surely it should work then?

@rubber_jonnie hopefully it will but the other board I have has a slightly different connection for the wires going to the CRT, nothing I can’t fix though.

In what way are they different? For the neck board or the coils around the neck?

@rubber_jonnie its the deflection coils plug that’s the main difference, the spare board has an offset pin but this one doesn’t. Then of course I haven’t got and radial 2200uf or 470uf caps to complete the recap.

I’m going to see if I can find a new HT coil for it. Something a bit like this.
