Bel Electronics BD80S help!

Hi, I picked up a Bel Electronics BD80s delay that is missing parts. I can’t find much out there about these in particular the schematic to enable me to repair the unit. If anyone has the schematics please could you share them with me? If anyone has an opporational unit would you be so kind as to send me a couple of photos of the circuit board so I can work out what chips are missing.

I’m keen to resurrect this unit since I hear great things about there sound.

Thank you, Craig

On poorly documented equipment, the only option is to find a working unit and see what is has and compare it to what yours doesn’t.

I hope that helps (I have an old iPhone S only at the moment - no camera)

Thank you, I am very very grateful. This really helps me.

I’ll let you know how I get on.

Best wishes,

Craig

This is really interesting. Was the transformer in when you took ownership of this? The +\- 15 and the +5 voltage regulators are not present. Very interesting.
