1. The Gear Page is run by musicians for musicians. We listen, we learn and if we misstep we are not afraid to do the right thing. We proposed some changes to the Emporiums. Based on feedback from members, we have decided to not go ahead with those changes. However, it has also highlighted that we need some community input into what is working and what is not working for members here. Primarily focused on the Emporiums, we'd like input on your thoughts about TGP and how things work in the Emporiums for you and how you'd improve them. The discussion thread on the is here!

    It should be fine with an amp like that. The only problem would be if the B+ voltage went up above the filter cap rating, but that's unlikely since EL84 amps have fairly low B+ (under 400V) and the caps are probably 450V types. You won't have to worry about changing the biasing since it will be cathode biased.

    It should tighten up the sound a bit. Maybe not drastically, and probably not noticeable below full volume. My Mesa Maverick has a tube/solid-state rec switch, and you really can't tell any difference at normal volumes - only when it's really cranked.

    I guessed that, and was just referring to the quote. And though Johns a bit of a high flyer, I didn't spot any actual wings when we last crossed paths. ;)

    Thanks again,

    Andy.
