I was looking at all the neat pictures out there of K3 assembly and I noticed a picture of the K3 Amp that has some resistors going from the binocular transformer...across the final transistors....to a solder pad. Looked kind of goofy to me so I thought I would ask. Are those some sort of balancing resistors and why were they placed in such a odd place (to me)?

Those are feedback resistors and dissipate a few watts of power. They
need to up in the air to allow the power to dissipate without burning the board. 73, Bob, N6CM On Nov 21, 2007 6:46 AM, Lee Buller <[hidden email]> wrote: > > I was looking at all the neat pictures out there of K3 assembly and I noticed a picture of the K3 Amp that has some resistors going from the binocular transformer...across the final transistors....to a solder pad.
