Negative voltage on the supressor grid...... explain please

[Bernardduur]

So, I was checking out the Peavey VB-2 amp for a friend of mine; simple rebias and checkup.....

I found that the unit uses a system to feed the bias voltage before the bias potmeter via 10k's to the supressor grid of the EL34's in the amp......

As for the tech help by Peavey, they told me this helps the amp to accept all EL34's and matches em to the ones placed.



As for now I only used to ground this supressor grid....... could someone explain the advantages and the disadvantages of this way? I am curious

I don't know if what Peavey said is very truthful.
Maybe in a simplistic sort of way,
Here is an informative post from right here at the MEF.
