What does a person have to do to get a schematic of a vox nt50h g2? It's like it takes an act of congress...

In regards to the vox nt50 biasing, did anyone find out if you have to install adjustment pot?

V3 and V4 are the bias pots for the two power tubes. Putting a voltmeter on each of the outside pins on the bias test point turn the pots so you read 35mV to ground.

Does anyone have eagle files for this? I'm trying to make one myself, but being a newbie on the stuff, I'm having a hard time.

I just purchased a vox nite train 50 last month, and i need to install replacement EL34 tubes that the seller sent me to improve the performance of this demo amp.
Do you have a schematic for the nt50, and if not, do the nt50 amps have a bias pot... i have not been inside the amp as of yet.
thanks for your consideration

Have you found out anything yet about biasing ?
Wondering the same thing myself. Looked inside and saw a bias connection with 3 prongs. center prong was ground. Saw two variable resistor pots, and thinking that these are the bias pots. But haven't tried this out because, as you, I don't really know what the prongs are reading or connected to, and although the resitors are likely bias pots, i'm not willing to gamble.

The output tubes in the NT50 needed biasing, when replacing them. It was confirmed by an authorized VOX technician.
