Bogen J330 Mic Input Problem

[Sylvaniac]

Bogen amps and their competitors back then were not sold in stores. They would have been bought from catalogs by contractors. The wrong gender XLR was just something they did. Standards were not as well developed back then. I wouldn't read anything else into it. If you asked someone in the mid 11950s what a mic connector was, they describe that threaded screw-on thing with the center contact. Switchcraft : Vintage Microphone Connector

I would swap out that male XLR for a proper female in a heartbeat. This is not a museum piece, this is something someone will want to use.

Ah, yes...THOSE! What a pain in the ass those were to wire.

Anyway, WELL spoken! More fascinating info. And yes I'm leaning towards changing out at least one male. Now I'm even tempted to in fact change out the phone plug, as g-one suggested. Even I know, the less junk in the signal path, the better the signal. And both these mods and can be undone to original, should I ever sell it. But that won't be soon, because yes someone will want to use and appreciate the amp--ME. I was strictly only into vintage radios till a friend splurged and bought a McIntosh MA230 / MC24 last month. Tube amps have brought me a whole new level of learning enjoyment. Thank you again!

Well, I mean, why did they have the male XLR instead of the common female XLR for the input? You know what? It could've been something as simple as an attention getter to make their amp stand out and be noticed in the stores! ???

I don't know if this is true or not, but an old timer, sound contractor that I used to do repairs for once told me that Bogen used the "wrong" input jacks to keep the average person from buying a mike and cable and just plugging it in. Any pro could make the correct Female to Female cable with standard parts, while anybody else would have to buy the cable from Bogen or plug in a clumsy Female to Female adapter. The later amps in the 60's also used an oddball speaker plug that was a pain to deal with.

I do know that back in the day Bogen equipment was very expensive and was mostly permanently installed in restaurants and schools, etc. as background music and paging systems.

Wow, Bill, interesting. And yeah my VP17X has these two prong speaker plug-in cables that are wired directly to the Jensen speaker. Good luck to me in finding these to convert them to terminate in lugs, for use with any speaker (but Ill rig something; a friend I have can maybe make these prongs from brass). I wonder if Bogen made that type of speaker adapter to allow people to use speakers other than the supplied one.

If anyone has a cable like this, no matter condition, if you'd like to sell it, give me a shout, please.

I think that is a 'Cinch Jones' connector.

Jazz beat me to it, I was going to point out those connectors are still available.

Oh, my God, this is a fantastic development. I searched and search for "speaker connector" and gave up, believing these were relics! THANK YOU!

Thank you, too. I'm glad I posted those pics!

Better yet! A buck cheaper! 697 in stock. I grab a handful. Bet one day these'll be gone. Thanks again, bass. (By the way, the bass rules!)
