Thanks, already downloaded their manuals -- indeed, I obtained the set via an ad on the EUG site!

Worryingly, the manual on there gives 1 V for the anode, whereas the EMER gives 90V.

The associated paper dielectric decoupling capacitors tend to go electrically leaky, further hobbling associated circuitry.

Thanks. Will look into the resistors and caps.
