    I have 3 old 6Y6 power tubes...an RCA, a Raytheon, and a Ward's Airline. The Raytheon is definitely a blackplate, and I'm pretty sure that the RCA is a blackplate, from what I can see through the smoked glass. Not sure about the Airline.
    Anyway, I've heard that these can be substituted for 6V6s in low wattage amps, such as Champs. I put one of them in my s/f Champ and it sounded good.
    Anybody else here have any experience with 6Y6s?

    I hope nobody turns around and says these are wonderful because I tossed a bunch of them in the spring.

    Not sure about a 6Y6, but a 6EY6 can be used in many 6V6 circuits with just a bias adjustment.

    The 6y6 is a 6v6 type and can be used in its place.It does not have the same wattage ratings and will make the amp clip faster. Its a common tube to swap in a Jim Kelley amp, as it handles the higher voltage well,
    and tames the volume a bit. I had some and used them in my Jk's when I had them. They sound good, if you dont need max headroom. The short glass RCA brownbase in familiar with. Not sure about coke bottle ones.
    Hopes this helps.

    i like how the envelope is lopsided on that RCA in the pic! At least it looks that way.

    I have used several 6Y6GA's in low wattage champ type amps as well as a few low wattage stereo's. I built an amp for my laptop with a pair. They are indeed very musical tubes and hold up really well, Or least say the 6Y6GA version does.

    I used a step up transformer to provide 220V which worked very well. They are definatly not a drop in replacement for a 6V6GT, or 6AQ5A but they are good tubes for low power projects. The Sylvanias I had could handle 250V but, I would not think the older ST style 6Y6's should be pushed that hard.

    i wonder what one would sound like in a fender outboard reverb?

    I'll take a sec to look up the specs to see how different they are from the 6K6

    looks like it might be a little risky but maybe worth a try. Definitely closer to spec than it is to a 6V6.
