Hi Turnip.
That scopey wopey not a Rigol is it? I keep looking at the Rigol DS2102..... thought I'd ask, hope you don't mind.
I acquired a box full of valves, all too good clod out, stacks of 6DJ8/ECC88 and IG3GT/IB3GT HV half wave reccy, good x-ray generators them but not as good as the PD500 shunt stabilizer triodes in them Flipips G6 chassis, hey am showing mi age here.
