Possible damage of a 5AS4 full-wave rect...

[Layberinthius]

The heater is at 5v 3amp which i've matched to a T.

I can see some heater flakes inside the tube moving around so there is a chance of causing 'real' heater to plate shorting and while fired up I managed to peek inside the plate envelope (rather long) and see some areas where the flake has supposedly fallen off... almost as if someone took a knife to a hot piece of metal.

I guess my main question is will I see any negative effects during high-voltage operation?

I get a reading of 3v across heater and plate with my multimeter.

Cheers.

Hi,

Ahhh...For all you know those could be chips of glass as well, but what do you know, he?
If it's really metal, junk the tube and get over it.

Sorry for being blunt, but try another 5AS4 to be sure...

Don't get paranoid over this, tubes are dammed tough beasts...
