HK Linear 5 112FA cab

[NHM]

Does anyone have a circuit diagram for a HK Linear 5 112FA cab (ours is about 10 years old.)

This cab has died and our tech says that he can probably fix it if he has the circuit diagram (which HK won't publish). Otherwise it's a new board which is £££.

Can anyone help?

genuinely dont think it exists even HK themselves dont have it so might have to just wing it mate
