Hi JPDuarte and all!


yes, i have 2 option PCB

1. Pure i/V balance with: 2 tube 12AU7+ 2 tube 6DJ8

2. Pure I/V SE with 3 tube 12AU7

3. HV supply for Pure i/V use one

Now you can see schema off Pure i/V SE and par list! thanks

PM: and some information about it with: Algar_emi post #217 DAC ES9038 PRO GR 2

Just a noob question: in se (3 tubes) schematics, what is the function of v3b triode? I see its anode does not output to any v2 triodes grid...
So a single 12au7 could be used for both channels, using only one triode per channel, i.e. the one that outputs to following tube grid?

More, sorry Quanghao but i didn't receive any message from you, something has gone wrong...
