  • Any schematic ideas for EF39, 6v6GT, ECH35, EBC33, EL33

    Time for a little experimentation

    Found an old radio in a junkshop today :-). The whole thing is D.O.A.

    But couldn't resist crazy impulse to acquire said junk. (I blame Enzo for suggesting a few months ago that I try an get hold of an old tube amp to modify - I think I might've gone a little off beam) One of the 6V6Gts has a crack in the plastic base, but its a neat looking tube - totally black inside the glass

    Was pondering some sort of simple guitar amp - with the exception of the 6v6GTs I think these other tubes are the sort of tubes that don't use an O/T, they've got a wire c oming out the top (please do correct me if I'm wrong, but I can only see one tranny inside the beast and that is next to the power supply).

    I thought I saw someone posting something about a simple guitar amp using these kind of tubes without an OT somewhere (was it here?) a while back - scratching my head?

    There is

    1 x ECH35
    2 x EF39
    1 x EBC 33

    These appear to be all Mullard types (well at least they're covered in red paint)

    1 x EL33 slot - that has been subbed for 6V6GT (the one with the cracked bakelite base - see photo following)
    1 x 6x5GT
    1 x 6U5

    Here's those pics

    There's what looks to be a good Brimar 6X5GT in there too

    (could one patch-up the crack in the 6V6GT? with some kind of silicon sealant or something?)
