    I would say Heppners. It looks like a 575 code. Fender used these.

    You can see that there were some legible in the photo but when I looked closely, I couldn't make any others out. I'll take another look though.

    It could be no-name brand. I gather there is much trading/mixing of magnets, baskets, motors and diaphragms between speaker makers. That said, I'm thinking Eminence Legend here.

    Is there a 328? That would be a Utah code- also used by Fender. The basket doesn't look like the usual Utah but they had some that did look similar.

    They are Heppners. I have a pair right next to me. They look exactly like that. The code is 12838G over 575817, which means 17th week of 196'8'. 575 is the manufacturer's code. Fender used many sources of OEM speakers including Heppner.

    Here's a good list of speaker mfg. codes:



    Common Guitar Speaker Manufacturers:
    • 67 = Eminence
    • 137 = CTS (Chicago Telephone Supply)
    • 220 = Jensen
    • 285 = Rola
    • 308 = Stromberg-Carlson
    • 328 = Utah
    • 336 = Western Electric
    • 391 = Altec-Lansing
    • 416 = Heath
    • 465 = Oxford
    • 589 = Bogen
    • 649 = Electro-Voice
    Some tidbits on Jensen: Fender used Jensen speakers until 1972 when all Jensen production (and one engineer) was switched to The Rola Company in Cleveland OH (Rola was a division of Jensen). Prior to the re-structuring of Jensen in '71-'72, Jensen quality had suffered terribly. When Rola started to make speaker for Jensen in 1972, Rola initially used the Jensen 220 manufacturer code, but by the end of 1972 changed to the 285 Rola code. Regaining OEM customer confidence after the Jensen years was a long process due to the Rola-Jensen ties.



    Other Speaker Manufacturers (thanks to P.Bechtoldt and H.Murphy):
    • 24 = Becker
    • 101 = Admiral
    • 106 = Allen-Bradley
    • 119 = Automatic mfg.
    • 125 = Bendix
    • 130 = Panasonic
    • 132 = Talk-a-Phone
    • 145 = Consolidated
    • 150 = Crecent
    • 169 = Hitachi
    • 185 = Motorola
    • 188 = General Electric
    • 213 = Dearborn Wire
    • 230 = Littlefuse
    • 232 = Magnavox
    • 235 = Mallory - North American Capacitor
    • 244 = Muter
    • 245 = National
    • 251 = Ohmite
    • 252 = Dukane
    • 258 = Perm-O-Flux
    • 260 = Philco
    • 270 = Quam-Nichols
    • 274 = RCA
    • 277 = Emerson
    • 280 = Raytheon

    Your welcome. It's a byproduct of buying too many speakers. Nice amp!
