krelldreamsIf your Alps pot’s passive pre, input to output measures 1.21kohm then you have a 5kohm Alps pot.
my passive across the input to the output as you requested. It measures 1.21kohm, which is as written on the bottom of the case.
Your source may well be doing it hard into this 5k load, and making things "leaner".
Passives should be at least 10kohm to suit "most" situations. Or higher (>10kohm) if the amp is also >50kohm or more.
