    Hi, if each of my two inputs are 20 watts apiece and 30 watts when run together on 2 6v6 what would my wattage be if I switch to 2 6L6? Asking because I'm running a 40 watt speaker. Thanks

    Inputs don't have wattage ratings.

    You have to multiply all the 6s in "6L6" and "6V6" for a total of 24. Then you multiply by the "LV" after converting from a Roman to an Arabic numeral. So, that's 24x55=1320. The correct answer is 1,320.

    What do I win?

    That's some math question. If I can de-quack what it is you are saying - You have an amp
    with 2 channels that runs about 20 watts with 2 6v6 tubes and you want to know what happens
    when you switch to 2 6L6 tubes? Assuming you will fix the plate voltage, bias and a whole host
    of other upgrades; and considering that a 6L6 tube is about double the output of a 6v6 tube -
    I'd say you would run about 45-50 watts with the 2 6L6 tubes.

    That said - you can't just drop 6L6 tubes into a 6v6 power section.

    Without replacing transformers, putting 6L6 in a 6V6 amp isn't likely to increase max power enough to be noticeable.

    Hang on now. He has the right to put whatever tube he wants to in his own amp. I think if he replaces the 6V6 tubes with 6L6 tubes, he will significantly adjust the output of the amp.

    Math eschews numbers. Arithmetic is all you need to solve the equation you seek. Poor humor from a Mathematician? Go Figure...

    First: The equation you are trying to find comes from an Electrical Engineering textbook. It is derived from V = I * R as all EE equations seem to be. The problem is that your situation does not yet translate to any equation... none that I know of.

    You are proposing substitution of deeply nested components... as such you are way over my head. My advice is to send a check to @papante and get his entire attention to your proposal. Good advice is worth $$$, so be careful what you take for free.

    Does anyone here think that a 50 watt Jcm800 2204 will suddenly produce 100 watts if you put KT120s in it?

    The amp is set up to take 6v6 or 6L6. I have an Eminence Alessandro speaker in it that I love and don't want to blow. It is a one off custom build, and built very well
    in my opinion

    If it's designed to run both you may get a bit more power with the 6L6s but nothing like twice -that's not possible.

    Then, all kidding aside, it depends most on what transformers the builder selected. Example: Allen Sweet Spot is about 18w with 6V6, 25w with 6L6. If Allen had chosen transformers a bit beefier, the 6L6 number might be higher, though the Sweet Spot might also be limited by the design of the Princeton-style phase inverter.

    It is almost possible, but it would mean the amp has much bigger transformers than a 20w amp needs.

    In the moment,.. hopefully.
    In certain cases it works that way. I have a THD Univalve and a Flexi. but the THD stuff has way over built transformers.
