Hello,
I have a restored ampilfier with an Astatic cartridge and a volume-control
with a 1 meg-log pot-meter.
When I turn up the volume the bass brings the cabinet in resonance and this vibration is picked up by the cartridge.
As a result a steamboat sound.
What can I do ??
I replaced the pick-up arm rubbers, baffle-board rubbers
and mech-board rubbers.
With a Wurlitzer 1015 its no problem but with a Peacock,
Wurlitzer 750 & 700 etc it is a nightmare.
Using a 100K pot-meter is losse a lot of power and bass ofcource.
Best regards,
Jo.
