    Hello all, hoping for a bit of help on a 1956 Wabash Deluxe I just purchased. I have not been able to find a schematic and unless someone here knows where I can find one I kinda doubt I ever will. It came with a non original 4 ohm CTS 15” ceramic magnet speaker. I’m trying to find out what ohm speaker is correct for the original output trans. Will measuring across the OT speaker leads tell me anything?....I did this and came up with 1.8 ohms.
    Also trem does not work...any tips on first thing to check?
    I did open it up and clean all pots an$ jacks, have a stash of new old stock tubes around so I did replace a few. It is 100% original other than speaker so I will at least replace filters. Most 8mportantly want to confirm what ohm speaker is correct though...thanks for any help.

    Cool looking old amp, post some more pics of the chassis and insides when you get a chance.

    Are those 6L6GA power tubes?

    Yeah pretty much a tweed fanatic... 59 Bandmaster, 60 Harvard, 59 Champ, the big blonde is a Billy Penn 3x10 59 Bassman circuit, not pictured is a 57 Deluxe. Just discovering the Dano circuits, not pictured is a Silvertone 1432 and now this Danelectro built Wabash, becoming a big fan of his stuff.

    Bluerolo, that amp almost certainly wants to see an 8 ohm speaker. There is a way to determine the turns ratio and thereby deduce what the secondary impedance is in relation to the tubes being used. But....it wants an 8 ohm speaker, ime.
    And...you might want to check this schematic against your amp, it is not an exact thing; but it appears that the two amps may have some things in common.

    There is a second schematic there for the input preamp section......which only has two channels versus the three in yours. Also, this Md. 89 does not have tremolo. I like that Wabash and would jump on it in a second. It would be of interest to draw the schematic. I just resurrected a 1966 Alamo Fury for which there is no known schematic. It is such an interesting amp that I had to draw the schematic. It is NOT a clone of any Ampeg amp as some on the ‘net have stated.

    Aerhead they are 6L6G tubes, I stuck a set of RCA 5881 in though. Thx for the schematic Wally, I've heard that the Series D Challenger is very similar, there is also a Montgomery Ward Airline that is either really close or the same amp, the 8438 model. Any tips on what to look for regarding non-working trem? thx!

    i was able to pull numbers off the output trans, it a Utah 1797 coded 328609, I’ve had no luck finding info on it...sure would like to confirm specs before I spend $$ on a 50’s alnico speaker and recone. Anyone know this transformer or a way to spec it out? Thx

    Just looking at the pics reminds me of the smell of my folk's old console stereo or an old TV that was full of tubes. It was a unique aroma, not unpleasant, more like wood that has been lightly toasted, possibly by hot tubes.
