Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE:I changed the plate resistor between posts

Ok, those numbers all line up like they should.

With a 56k ohm plate load the load line will be pretty horizontal but with only 3.4ma of plate current that tube will not be as linear as it would be if there was more current.

More current with a 56k ohm plate resistor would take a lot of B+ (supply) voltage.

A CCS will give you your cake (a horizontal load line) and you can eat it to (get about 10 or more ma. of current going).

Then that tube would be very linear (low distortion).

Just something to think about.
