    Betty Butt
    Bella Butt
    Beth-Sheeba Butt!!!

    ...they called it the Bertha Butt Boogie...
    No question!
  2. Glued-on wedges are correct, except on very early version.

    Glued-on wedges is the factory method of attachment. :yes: The exploded diagram doesn't reveal this detail, as the 2405 horn is an assembled part.
    The outer horn is actually an 075/2402 machined...

    I feel your pain... however, considering their age, the nickel plating hasn't done too poorly, has it?

    On low-voltage contact points, oxidation can produce a "diode effect" that can make for a nasty sound quality due to the fact that the oxidized surface is resistant to current flow below a certain...

    Vintage Crest amps too!

    Crest Audio was started by former BGW employees, and a brought a lot of the same thinking into their amp designs, like their 'overbuilt' power supplies.

    Thanks Mitch.

    I posted this thread 4 years ago while helping a customer with butchered-up SRX715's restore them to order. At the time he elected to save $200 with used 2432H instead of used 2431H....

    2435H is a whole other animal... no comparison there.

  15. Greater moving mass could be the culprit

    It seems to me that a higher mms figure, such as what a copper coil substituted for the aluminum coil would undoubtedly contribute, would result in a higher mechanical resonance... which in turn...

    One step below VGC 2206/2226/2241

    Those are either MR835 (2118H mid, 2416H HF) or MR935 (M209-8 mid, 2418H HF and "Sonic Guard" light-bulb power limiters for HF ckt)
    Networks are different, matched to the drivers they have.
  21. Nice little score!

    Do those have the AlNiCo magnet woofer in them? If so, be careful powering them with that 6290. Get a little too happy with the levels and you'll start demagging the AlniCo.

    Speaking of 6290, I...
