How does a tube amp work?

    The speaker manufacturer decides this. But Gordon's helpful response to this query in post #107 explains why a 25W tube amp might work as well as a 100W SS amp for any particular speaker. His points are that tube amps can run closer to their max output before clipping, and a 3dB volume difference does not sound much louder. 'So, if you have a 25 watt amp which you can "use" to 24 watts, vs. a 100w amp that you can only "use" up to 50- that's only 3dB difference. Not that much perceived volume difference at all...'

    The manufacturer gives a recommended range, but I have used many speakers below their minimum with great results.

    But you'll still use SS stuff up front because it still has a better variation on tonal differences and easier to manipulate without changing everything in a tube preamp.

    That begs this question. Since I only have 10 watts at most.
    What % of power can I run my 10 watt tube unit at? All day all night. 24/7.
    90%? as long as it sounds good?
    No I could never run a 50 watt SS unit like that could I?

    In the tube era, PA amps, radios and TVs, were all designed to run for long periods of time without difficulty. So, you can run your amp 24/7. Whether you want to run it just below clipping volume is another matter, unless you are running a dance club.

    I would never leave a tube amp on unattended, even if it had been completely rebuilt, for eco and safety reasons.
