RE: If you need precision current bias of power tubes...

You are certainly right if you are also looking for maximum output power.

I am rather focused on serviceability of the hardware.

Only a few tube experts are now able to carry out the periodic adjustments of power tubes.

So the lesser current controls are present, the better.

As I said, with 'current sources' you can eliminate adjustment pots.

Have a nice day.
