DC voltage on outputs on F5

[Zen Mod]

They do not meet eachother, actually. The outlets in my house does not have ground, so I have not connected the gnd of the inlet to the chassi, nor the power PCBs or the amp PCBs. Not "safe", but since there is no gnd connection....well.

As far as I can tell, the 18vac output on transformer one is floating in reference to the other. Am I wrong?

it's obvious that I can't explain in few lines , so either do what I told you , or leave it for some time and read some books with electronic basics
