  • I remember that mod,, one of the toughest that I have ever done,, but it brought it to a different level,, for the money,, this is a no brainer,,good luck with the sale,, bet it’s gone before the sunset!
    Looks like I now own this, so I’ll need to read through your original upgrade thread closely. Was the extent of the upgrade the 6 caps?

    Thanks, Skip. Lots to learn as this is the first tube amp I’ve actually owned.

    I am pretty sure I just bought this exact preamp from you. Happened to stumble across this thread...

    Ha and welcome to the forum! It's a cool place with a lot of audio knowledge.
  • Where’s the right place to ask newbie questions (like is it cool that the rectifier tube gets and stays super hot overnight)?

    Wherever you want. This forum is much more laid back than most. I usually post stuff dealing with two channel gear - speakers or electronics - in the 2 channel section.

    Well yea a rectifier tube is going to get very hot. My question would be are you just leaving it on to stay on or ??? I would just turn it on about 30 minutes before use and shut it down after I'm done.

    Or are you asking that once shut down it is still very hot the next day? Your question now that I've read it 3x is a little confusing

    Shut it off. Give it a warm up period before you listen. Your tubes will thank you. (longer life)

    I assumed that it's normal for the rectifier tube to get really hot, I was just surprised how hot it still was this morning. You got the true question right: should I leave it on 24/7? I've read a lot of opinions on this, and there doesn't seem to be a consensus. Thanks for the input.

    My background is I've owned one of these on probably at least four different occasions. I always shut it off and let it warm up for about 30 minutes before each session. Yes, it does get warm.

    So sorry but I'm not getting the reason to leave it on. Maybe for a mind greater than my own.

    FWIW, I wouldn't leave a vacuum tube component on all of the time -- at least, not one using a vacuum tube HV rectifier. The risks, I'd opine, outweigh the benefit.

    Hot as they get (and they get oven temperature hot), the HV rectifier should cool off relatively quickly (a few to 10 minutes or so) after the preamp's shut off.

    If the HV rectifier is hot after the preamp's been shut off overnight -- something is either very weird or very wrong, I'd opine.
