Memory Problem Dual Deltafex

Post by Adrian Lancer » Fri Jul 08, 2022 7:43 am

My silver face Dual Deltafex won't hold memory anymore. Is there a battery inside the unit or am I consigned to a manual input every time?

I am relatively confident that all those old fex amps had a battery in them.

Open it up, drain any power supply filtering capacitors, and take a look around. I think most were the computer button cells, 2016, 2032, etc.
