Interesting. Here's my PT : http://www.classictone.net/40-18029.pdfFirestorm wrote:The 5V4 would almost work, but you don't want to arc one. Interestingly, the GZ32 is usually considered equivalent to the 5V4 and according to the Philips datasheet would certainly work here (250-275mA at these voltages). Strange that they would also nix the 5U4, which can easily deliver the current, but would sag the supply a bit.
It shows the voltages for 5U4 and GZ34, implying 5U4 is doable.
FWIW, I'm using the red/white taps and have 400V B+ ww/ SS.
Miles is right, I am slowly converting to the stiff dark side
