Using BOZ to drive a 20K load.

G · 7th July 2004, 01:36 PM

Does anyone have experience with using the BOZ to drive a 20K - 50K load? How did it work?

Is anyone on this forum polite enough to reply or hazard a educated guess? I promise that if you need an opinion or some help on the tube forum you will get an answer.

You probably didn´t want to hear a question on this one...
But why should the BOZ have any problems driving a 20-50k load when it´s output impedance ranges from few to 1.5kOhms?
Mmmh, maybe you wanted to hear something about sound...

It´s probably magic but some will call it single-gain-stage.

I build tube amps. I don't have a problem with single gain stages.

I'm trying to decide if there are any modifications that would make it work into the high load better. That's all. Not real familiar with Mosfets. Just wanted a couple of opinions or suggestions.

Isn't 20-50K a very comfortable load for the BOZ to drive? It should work fine with pretty much any load over 1k. And high signal voltages are not a problem with this circuit.

You are probably correct. It should work fine into a higher load. Plus I will be able to decrease the size of the output coupling cap to something a little more economical.
