Title: Simpson 260 Repair
Post by: W3KC on December 24, 2018, 06:43:44 PM
Does anyone know if the zero ohms adjust potentiometer (R25) in the Simpson 260 series III is a special taper?

I haven't worked on one for a few years,   but  wild guess would be   linear   taper.     O scopes and instruments usually  have linear taper controls..
audio tpaer is used n  audio equipment  becasue of the way the human ear  registers  volume increase.

reverse audio taper is unlikely..
