Attention: fup2!

Hello,

In an older power supply unit for GM counter tubes, the high voltage
(max. 1 kV) is generated by a normal push-pull voltage converter
(switching frequency approx. 8 kHz). In the HV filter chain, this

capacitor is connected in parallel with the following strangely
marked component of the same size,

which my Far Eastern multitester identifies as an 8 nF capacitor.
That could well be the case, but why the strange marking? A VDR? What
do you think?

Many thanks in advance for your hints.

Best regards

Reinhard
