I had one of these amps at one time.
The tube is indeed an ECC91. You can also use a 6J6/6J6A/6N15P equivalent.

Vincent SP 331 MK tube ?
I need to identify replaceable tube in my Vincent SP331MK. I know the soldered tubes are 6N16B. every one (including Vincent web-site), says it's 12AU7 or 6NIO. It's neither. Tube in my amp is smaller with only 7 pins. Can't read # on tube, so I'm stuck. Can anyone help or refer me to someone. Can't speak German so contacting Vincent directly is out. Thanks for your time.-----Mitch
