Got the "R" version.
The V12R in not only a nice sounding amplifier, it looks the part too. A rare and interesting piece of audio history.
Running NOS Sylvania front-end tubes, Mundorf EVO Silver-Gold coupling caps, EL34-BSTR power tubes, sounds great in 50w triode or 100w ultra linear mode. Mate it up with a Cary SLP-98 tube preamplifier with NOS tubes and it's magic.
