Hi,

I have a couple of 5755 tubes and would like to use them for both the first mu-follower and the second one. Can it be swapped in directly, with only a change of pins? Or should I use values of the first mu-follower for it? Would it affect the sound drastically?


I also have a couple of 0D3 (150V regulator) I plan to use to regulate the 300V B+. Is it safe to have a large capacitor like the 47uF in the Phonodude connected with only a 3k3 resistor in between? I plan to use the EZ80 or 6X4 for the rectifier.

Thanks! :D
