Re: yamaha t50c hum
Just want to bump.I know the middle of the video is a racket,overloading the camera.The first 30 seconds,you can really hear the ghost notes.Anyone ever encounter this and if so,what did you find ?

Re: 2Watt Sub Miniature Plexi
Sounds great Dana !
I'd like all the major parts(boards,chassis,front panel,xformers,tubes and sockets),I can mouser the components(especially with your recommended list).

Re: yamaha t50c hum
It was there from the beginning.I was hoping that when I worked on the amp,I would stumble across it and fix it.

Re: yamaha t50c hum
Chopstuck,
I also changed the speaker.Mike Soldano told on a phone conversation that the amp was designed with V30's in mind.I put in an Eminence Governor(similar with less shrill).This make a HUGE difference in sound with this amp.Good or Bad is up to you.
