I have an amp running 2 X 12AX7s, a 5751 and a pair of EL84s that works beautifully however when I switch from standby to on I get an arc in the 5Y3 rectifier. Is this likley to be a duff tube, should I be concerned? The amp runs perfectly once on and there is no sign of any other arcing, the voltages are all good etc.

Nigel,

It looks like there are some guys talking about this over at 18watt in this thread . I can't say that I have had a rectifier arc, but then I can't recall ever really checking :lol:

The vacuum in that tube is probably 'gassed'. You can use it, but replace as soon as you can and trash it.
