    Question Pre-EB Preamp problem-- HELP..!

    I have a 77 Stingray and the epoxy preamp just shot craps on me, need help quick! I read sometime ago on this forum that Ernie Ball still had some of the original preamps available, just need to send in old preamp for trade, is this true? Can someone answer this for me? Any Help appreciated. Thanks, Randy

    I believe they did find some old stock black epoxies. Contact one of the techs at EB.

    Can you explain exactly what happened to the pre-amp?

    P.S. let me know how you go....mine recently cut out but came back to life....I have a feeling i may be in the same boat as you very soon.

    Derek....you're talking about the Ernie Ball 1985 to circa 1990 pre-amps styled on the old Pre-EB MM pre-amps....right???....not the 2 band EQ circuit introduced thereafter (with the crescent moon-shaped circuit board)...which we see today on 'Rays with the 2 band EQ option??

    Derek...if I can add....one of the techs has them in a "bucket".

    Also, the EB 2 Band (1995 to circa 1990) is bassed on the the 1979 MM NON-epoxy circuit (I believe) which is a completely different situation to the epoxy version.

    (uuuuhmmm....it's 41 degrees here at the moment....I might go and have a beer).

    The original 2 EQ pre EB preamp(1976-79) is what I was going to check on. The Tech's are off today(FRIDAY) so we will check with them on monday.

    The preamps we do have(normally) are for later versions Stingrays 85 to ??? Anyway I will get it sussed out and give you guys the details on what we have available.

    Randy,

    Ok here's the scoop! We do not have NOS Pre-EB Stingray preamps. We do have about 100 or so pre EB Sabre preamps. They are from the 7O's and do contain a element for a bright switch, and are not exactly the same as the Stingray preamp. We use these for Old Sabre Replacements when they come in for repair.

    We do make a replacementpre-amp for the Old Pre EB Sting Ray .

    Here is the description from Dudley in our R+D department:

    The 2 EQ preamp that we have on hand are exactly the same circuit as the original,except that it has a 1k ohm protection resistor ,which keeps the IC from being shorted. The old ones were notorious for blowing the IC when the output cable was shorted. The New preamps also have electrolytic capcitors,rather than the tantalum capacitors the originals used. Tantalums were the hip new material back in the day ,but they are not the best choice for audio.

    If you would like to get one please call customer service @ 866-823-2255 x 126
    (They will not need the old pre amp back in exchange!) Correction!!! We would still require to have the old pre -amp back to make sure the new part goes into a MM bass.

    Thanks

    Derek
