Yes, that driver tube is what Robin and Lipman published in 1947, 6SF5 DCed into a 6B4G. .
Better driver tube choice is 1/2 a 12AX7, it is plentiful, so you can "tube roll" ( Telefunken smooth plates, Amperex, Mullard, etc etc etc. )
Additionaly, I discovered in 2014 that higher mu triodes that are octal based ( 6SF5, 6SL7 ) SUFFER slightly, just from having eight soldered connections, to the Octal pins, that is HEARD as a degrade in ultimate clarity and resolution, compared to a more modern 9 pin miniature triode. Diction suffers, ultimate resolution suffers on voice.
I have A-Bed this. With the better tube-type choice, its extra clarity for free, IF you are conscious to make the best tube choice decisions at the onset. You can sub 1/2 a 12AX7 for a 6SF5, not any problem what so ever.
If you contact me privately, via email, I can send you information and suggestions to directly apply to your Type 45 build, …..IF… you elect to do a DC amp. I can even refer you to others using Type 45s, I have helped.
Its not "for peanuts" that you build an amp, but I am an amateur and I advise for free. I know I can provide you the best bang for the buck in performance suggestions, that will fit within your tight budget. I have enough experience to do that.
