It only needed a new cap for the internal reference a few years back. The downside is the 32mA output, almost 32mA more than 1 need. The output is in series with a relay that should eventually kick in above the 32mA. Colleague got a shock from the his 3kV version once (415B), he was not amused.

Did you mean a Fluke 412B? the HP 41x Series are all meters not HV supplies.

I have loads of test gear with vacuum tubes in my collection, mostly HP, but I also have a Farnell E350, Advance SC1 and a few older ones from Taylor.

And i saved a magic eye valve from going to the rubbish tip a while back.

Gave the only one I've ever had to member Neo in the US as I'll never use it.
He had some project but has never disclosed what.  :-//

Still got a box of assorted tubes that I really must throw out unless you want them ?

Only if there's some 12AX7  or EL34 in there.  ;D

I think there might be, I'll look tomorrow and PM you.
There's all sorts of old shite, some was Dads from the '40's but most were scrounged from old tele and radio sets.
There's a few bases too, 4, 5 and 8 pin along with some later mini 8 pin bases.

I have a Keithley 240A power supply.  I don't get to use it very often, but love the fact that it goes up to eleven!
