    Trouble finding a Variac

    Hi all,
    Requesting for a bit of help. Im currently after a variac as the other day was testing a tube amp and as soon as I plugged it in 3 of the paper caps blew up in my face, after rethinking carefully what I had done wrong, figured it was because I brought them up to line voltage too fast causing them to explode. Don't suppose any one knows where I could get a hold of a variac it needs to be capable of 240 VAC @50-60Hz roughtly. If any one has any ideas where I could obtain one let me know thanks.

    lol
    i would have re-capped it first.
    some stuff simply should not be preserved - ancient caps are top of that list followed by rubber-insulated cables.

        i'v seen lots of caps explode - you *never* get used to it!

        closest i'v been was about 3ft from it - had to pick bits of paper & foil out of my hair afterwards!
        bastard xenon strobe lights really piss me off!!!!

          Lol it left some crap on the floor that was sizzling smelt horrible as well yum....
          Alot of them I can use some radial lytics I have around but before I do that I need to replace the following:
          Rectifiyer think its selium
          Every wire with high quality braided wire
          Caps
          Carbon resistors
          Possibly tubes need to test them on mates meter

            You should read up on tube equipment safety... you're lucky only the paper capacitors exploded. The big can electrolytics can go too, if they've been sitting around for a long time. You don't want a face full of toxic oil!

                Now its a case of seeing if im able to fix and restore it, going to have to put it aside for the min as got other things to focus on will be fun to do though.

                    What particular amp is it? Have you looked for a schematic?

                      Trouble finding an NEC IC
                      by lethbrp
                      Guys,

                      Can anyone help me identify this IC, it's connected to a thermocouple on a heater controller. I'm trying to find where I can get a replacement and a data sheet. I believe it's from NEC, but googling has drawn a blank after that.

                      Best regards

                      Use of a Variac to slowly power up equipment
                      by tony359
                      Hi all,

                      I have an old Apple II monitor to restore and I do have a big variac. I've always wondered whether a variac is a good idea to power on equipment which has been unpowered for (likely) decades?

                      When it comes to analogue stuff, I suppose it's ok and I'm probably going to see the device slowly coming back to life with a lower voltage applied.

                      But I suppose this won't work for devices with digital components in it as they won't work unless the proper voltages are applied?

                      In case of an old monitor, it is safe/good for the monitor to...

                      I got a Lenovo Legion Y7000P IRX9 with no fan power.
                      Found a shorted line, IC explode.
                      No boardview or schematics available, but i'm unable to identify it to be able to replace.
                      ​Can someone assist ? ...

                      Variac Transformers and switch mode power supplies.
                      by angelos
                      Hello everyone,

                      I was wondering if anyone in the forum can tell me how they use the variac transformer to check a switch mode power supply that they had just repaired.
                      I wanted to know how they adjust the votlage, do they start from zero and turn it up slowly or rather switch on that about 60V ac ( My country we use 220V ac) and hope for the best.
                      Also what sounds the PSU should make, what sounds wrong etc. Also if i have a scope what can i check for.
                      The reason why i am asking is i have a Sony LED TV PSU whose PFC circuit shorted out and upon closer inspection a...

                      Fixing a variac with shorted windings
                      by CapSnap123
                      I have an old "Adjust-a-Volt" variac. Shortly after I bought it, it started smoking and now the windings look burned for about 2 inches around the left side. Is it possible to fix this or bypass the shorted windings? I'm not sure how to detect where the bad windings are, except by appearance.
