I found a tube in my stash that I should build an amp for...

    It's an old GE ECL86, preamp and power tube in one bottle. A little one tube SE amp would be cool.

    I did something similar recently. Found a full can of Olympic white spray paint I'd forgotten about and figured I'd better build a Strat.

    The ECL82/6BM8 are a similar dual triode/pentode tube. Lots of information is on the web using that tube. You could use those schematics For ideas.

    I’m surprised a guitar amp maker never use them for a reverb driver and recovery tube in a guitar amp reverb circuit.

    I remember a ‘discussion’ I was in years ago at 18watt.
    6BK11-2 triodes for preamp
    ECL86 for reverb
    6BK11-3rd triode for cathodyne PI
    6DZ7 for power tube(s)

    15-ish watts w/reverb from 3 tubes.

    That is a great idea. The demo sounds excellent for a low volume amp with some hair on it. Schematic included so everything needed to do one up, thanks for the idea and info.

    ^^I'm glad you said this first^^:twisted:. I've dumped most of my old car parts to keep from this very vortex of budget busting rationale.

    Ah yes a spark plug from an old Ford pinto. Must find one to restore. This is why I'm thankful I've never been a car guy. All of my guitars, amps, tools, and parts combined come out to about the amount of one decent car.

    These tubes were used in TV’s for the audio part of the tv. They provided long life and could run daily for 10 years. Not very expensive for what this tube seems to be able to deliver.
    As a small amp the iron required should not be all that big, you could make a compact one tube head. Iron that size should be easily found in an old radio.
    I don’t know if this is of any use, I don’t understand any of it.

    I love this thinking on here! Build that amp!

    "Well, I found a nice string tree in my parts bin..........Better mock up a jazzmaster"

    I encourage it all

    Yes I thought about the car thing briefly, mmmmm a minty 60’s Chevy Nova. And your right stick to the small stuff, I could have a dozen amps and guitars easily and take up less space than a Pinto. Well if I stacked them up that is.

    Hahaha I literally typed out chevy nova in my post but then changed it to Ford pinto because I thought it sounded funnier.

    Not as a reverb driver, but in a cool BF-esque application -
