[Elecraft] K2 sidetone

[Hans Johansson]

I am the happy owner of K2 #5169. It functions fb but I am
very dissatisfied with the sidetone.I have read all posts on
modifying the sidetone and done all of them but I still have'
thumps on the sidetone. It's not a big problem at slow speeds
but when I work 30 wpm or more it is very irritating. Is there
anyone who has fixed it please tell me how to do.
I am on my way to give up and build a separate sidetone
oscillator ( a copy of my excellent OMNI V osc.).
My second question: Is there any point where I can find 
keyed 5V (or 8V or 12V) ?
