Fun stuff today. I played with the new 7591A valves. While they were purchsed as a matched quad, the bias required for equal current varies between 19 to 21 V, (for 32 mA standing current) which is close enough to the maximum of 24 V available, and quite a bit higher than the original bottles.
They sound just fine and in appearance are very close to the old bulbs. Enjoyed a blast of different music whilst working on other things. I need to add the new dial glass and take a picture or twp to complete this thread.
Cheers,
Ed
