Thomas to avoid any mistake I have to connect B+ to pin 18 & pin 13 to plate, pin 8 output positive & pin 10 output negative?
Felipe, I don't understand it.
Please sketch some schematic.
ps. : some posts are missing?

I try to implement Ikoflexer CCS+gyrator, better if post him. Staffan could you post your schematic or your used schematic.
I dont have any specific schematic. I have a breadboard somewhere with some 3-4 A 200ish mH chokes for the katodes, just to see if I can build something that matches Rods optimum sand-stuff. 1660 PP was thought for the anodes and I usually start with conventional stuff before I implement the special made goodies. Just to learn the difference and hear the eventual improvement. Otherwise its as most on this thread. 5-6 mA on the curve, I dont remember the voltage.

Don't forget I have another CCS in front of Salas regulator, plus VR tubes, the tube is running at 4,5mA.
No, Salas + CCS + VR.
I had both, and I don't see any harm on it, and the VR tubes look wonderfull.
See Ale's schematic on his blog, #26, version 2.
I would recomend sometime to bypass the VR tubes and try the salas regulator directly on the load. Maybe you like it netter like this, or not. It' s going to be an interesting test anyway!
hi, i have a dac with an output cap ( 2,6V offset)can i use it with the 26 preamp in direct coupling mode just putting a bigger filament bias resistor to have 10V between grid and cathode?
thanks🙂
thanks🙂
