Need digital board for Electro 2
Apparently this part is unavailable from the manufacturer because of the age of the model. I can still play the instrument, but if I hit one of the “drawbars” I experience a sudden volume drop. The tech who worked on it for a while said that replacing the main board was the only way to fix it. Is there any place I can find one?

Re: Need digital board for Electro 2
I find the title of this post confusing because the NE2 contains a Panel board and a Main board (both of which contain a mixture of analog and digital circuitry). The text of your post says "main board", but the Drawbar switches and scanning reside on the Panel board, so that Panel board seems to me a more likely culprit than the main board.
Both the Main and Panel boards play a role in scanning the Drawbar switches, so I want to make sure you get the replacement board you need.
If for example, the Panel board has a stuck bit scanning one of the "IN" draw bar switches (those that cause the draw bars to illuminate fewer LEDs) it could cause the behavior you see... This scenario manifests as four draw bars to collapsing to zero very quickly resulting in a volume drop. You might be able to try this from a preset or programmed organ setting.
You say you hit 'one of the "drawbars"' - do you mean one specific key or any drawbar switch? My scencario above assumes one specific key in Organ Mode.
Does this only affect organ mode or does it lower the volume in Piano if you hit a drawbar switch?
