Just a final question on this, I can live with audio-nervisa but don't want paranoia to boot. If something had shorted then would the thing not be working now? Or, is it possible for a short to have only the slightest effect on the sound being produced (now I know that is paranoia)?
Cheers

What is 'the schema'? A tube tester? Voltmeter? Sorry, I'm without a clue on component DIY. Are you suggesting that there may indeed be a problem, even though the change to the sound is seemingly so subtle?
If you like to live dangerously, after all it is only a player, dont take it to someone who knows how to check it... ;)Antonio Melo Ribeiro
Soooo, I should have it checked? Even thugh it's working now something might blow in the near future because of the manner of the tube-change? I don't really get it, there seems to be a fair few cryptic responses on this thread (or maybe it's me), but I will take it someone who knows how to check it. Anything he should be looking for in particular because he's likely to say "it plays music, so what's the problem?"
Relax and enjoy your music.
Its not like running a motor without lubrication.
It would be easy to short one of the tube's pins, especially if your sockets have a metal post in the center.
I've hot swapped quite a few 6992s in an amplifier when the manufacturer said it was OK to do. It used "global-feedback". Retubing it just required minimising the voltage difference on the last dual triode.
And, remember that you probably have at least 100 volts that can wake you up if you slip! The bite won't be bad. But, you can develop a habit of not pulling your AC cord before changing tubes, and some day, do that with an output tube with more than 100 volts on it.

If the tubes are not ON in stand-by, then you should be OK...
