PrimaLuna Dialouge Premium - Technical Design

I wanted to ask some questions about the PL that were not part of a screed about rare failures.

As I understand it, the preamp is true dual mono and each channel uses:

• 2 rectifiers
• 3 signal tubes

I'm curious of anyone knows about the audio circuit? That seems like a lot of tubes to my eyes for a single ended design.

Also, can anyone validate please what the coupling caps are now in late 2017? Are they Mundorf SIO?

Thanks,


E
