FL2100Z test after new tubes fitted.

Update note. Measured plate voltage with HV probe, around 2380v, so Amp HV meter reading a bit high on the front panel. Had my mate Brendan a bit concerned, me too til we checked....I think we said 2.6kv on the video, 2.4kv is more accurate, I have seen them even a bit lower. A bit of 572 valve data below the comments..

Had this one in for a restoration with a few handiwork bits to be done for a very good mate of mine. Beautiful amp, and she has some nice new tubes working incredibly well.
