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
