Hi all am looking to change the 5687 valves in my Tron Seven GT spec linestage ,currently have matched Sylvania 5687 WA which the designer recommends due to there quietness.I wondered what recommendations there wer out there for alternatives, I have read good things about 5687WA Thomson CSF (French) (Bendix 6900 beaters etc).
Was conidering Sylvania GB-5687 but have read that the Sylvania GT5687 & 5687WA are very similar.
Any suggetions would be appreciated but they need to be quiet...
