Solid State
Hi Nathan
Yes, i do have the service manual for the Fabulous 89, although its fairly vague and states that any service to the solid state controller was limited to the pressure switch and indicator lights.
I have the advert for the first model of this and the solid state controller is shown to be a printed circuit board on a round cylinder attached to a motor for rapid advance.
The chances of me finding this machine intact are slim, the solid state circuitry gave problems due to moisture from the hot water and eventually, many entire control panels were replaced with a more standard rotary dial set up.
But, i'm not giving up.
