K200A-4 Tremolo Popping [message #16593] Wed, 18 January 2012 20:01   Roy Messages: 11 Registered: June 2004 Junior Member I just completely re-capped this amp and the tremolo/vibrato pops when it is switched on. Any ideas what would be causing this? Thanks! Report message to a moderator

Probably was, as this is fairly common in both the A and B series amps. Kustom used standard transistors as signal switches to turn on and off the FX. These transistors sort of slam on and off and will cause this sort of popping noise. Some transistors are better than others, you may be able to swap them and see if the noise is any better. I wonder if shunting them with a high value resistor would equalize any built up charge and reduce the noise? Report message to a moderator

The tremolo was not very audible before the recap, so I did not hear any popping beforehand. Thanks for the tip about the transistors! Report message to a moderator
