Where are the bias reading points on the VH4?

[SadisticMagician]

So I've got my plate voltage (471v) and I've got the tube wattage (38), now I'm ready to do the bias adjustments but have no idea where to read how hot or cold the tubes are running at.

Most of the amps I've worked with before had external bias reading points.

Doesn't look like I have any external points.

The instructions are confusing for me.

It almost seems like he's using the same process to describe getting the plate voltage as he is reading the bias.

Is this correct?

Sorry if some of you are confused, like I said this amp is very different from my previous ones.

Check the instructions on the Tech Corner of the Diezel website. In your pics - the top right OT is the one by which to test the sides for biasing. 2 sides with the black wire in the middle, then a red to one side, and a yellow (I believe) on the other. Just check the site though - I'm going by memory and not looking at the underside of my amp right this moment.

Peace, and be careful...

Weird, this is the same way I got the plate voltage reading the first time.

I figured out what the instructions were saying, forget it.

I'm all set, thanks.

Very soon!

I was confusing the shunt method in the instructions as a way to get plate voltage.
