    Everyone knows that a transformer will burn first to protect the fuse.

    It's apparently the Bugera design philosophy.

    If you read from the beegining of thread sems that some users say that even the PREMIUM match quad set dont make a sound difference in guitar amp and apparently tubes burn with different intesity, non equal! So in time they are all different.
    Correct?

    Very cool. :thumb: I know the name Varian well & yes we had even bigger Tubes, from memory we also did a 4CX 20000. We must have had similar equipment, albeit ours on a smaller scale.

    We'd strip these Tubes & completely rebuild them for another round.

    We also made Tubes for Military applications. Those were the days when we actually made interesting things rather than shuffle paper & clip the ticket on the way through. The Plant I worked at used to make TV's, Speakers, Amps, Phones, Military Gear, Power Supplies, Digital Data Network Equipment & the list goes.

    We even had our own Winding Room where we made Transformers the size of a Marble all the way up to big Iron, along with Wax Tanks under Vacuum. We also had a Plating, Paint Shop & Stamping Shop.

    It was my first job out of University. Now what do you we have? The entire site was knocked down, about 2 Blocks worth & replaced with housing. :shock:

    :cheers:

    Old thread but its related to my situation.
    A guy is selling and amp.
    I want to lower the price so I asked him in how bad shape the tubes are...
    He said that they are fine but he hasnet changed them for 2 years now.
    He said hes an occasional player.
    Any chance I could determine how much life is left in tubes?
    If not much, I could lower the price....

    That is not a valid strategy for a better price, imho.

    Make your offer, he takes it or leaves it.

    What amp? What tubes? Modern amp and modern tubes, it won't matter anyway.
