Ampeg Isovent - Jack Plate Circuit Board.

nothing wrong with it, but having an Isovent cab is not even vaguely like having a B15 (or B18).
one is a well forgotten, poorly executed bass cabinet that does not work very well and pretty much nobody cares about (for good reason), the other is a truly iconic, great sounding bass combo that has been used on thousands of recordings for more than 5 decades and is a highly sought after piece of vintage gear (for good reason).
you are welcome to your own likes and dislikes, but you can't invent your own odd, knuckle-headed reality and expect anyone to buy into it.
I could easily walk out of here and buy a refurbished B18 with tube amp.
To me it would be an extravagance if I had a whole lot of extra money, but since I dont, I wont.
I like the Isovent Concept, even if you don't, and I am Keeping it - within the Reality of my home.
If you don't want to buy into it, then don't, and I assure you, I won't be losing any sleep of you don't, because I got the Isovent for my own personal reasons.
The guys who were of assistance regarding my questions - I appreciate.
As to guys like you?
Well you have your life, and I have mine, this is a Big Nation, and disagreeing shouldn't be too much of a problem.

By the way, I like the Genzler BA15 but they are expensive.
Maybe gradually I will get one.
For the time being I have Other Financial Obligations so something like the Genzler goes on the long term goals backburner for a while.
I think I will just gradually sock away some money towards getting a Genzler BA15 rig in the future.
If I find myself doing a whole lot of serious gigging then maybe I will change this agenda.
Well, the Genzler, Mesa, Bergantino, etc. are relatively expensive for a reason. They are newer, more sophisticated, lighter weight, more efficient, and better engineered than many of the less-sought-after amp & cabinet designs on the market - like the IsoVent.
That's not to say you can't find used gear that suits you perfectly for very cheap, but you typically get what you pay for with older gear once you get away from some of the more sought after vintage stuff that retains market value because it still holds its own.
If you really want a Genzler rig down the road, why not play through the amps you currently have at home & stop investing time/money into an obsolete piece of equipment?
Edited to add: People like AgedHorse are why we have the luxury of carrying around enormously powerful, lightweight amplifiers & highly efficient, 30 lb speaker cabinets today. It's already been said, but the guy who has tried to offer you very sound advice has not only seen the evolution of these audio systems - he's helped to make them a reality.
Also worth noting is the fact that many of the Neo, Class D, and other lightweight designs we see today are driven by the preferences of a sizable subset of bass players. So you have to consider that there's a reason the IsoVent is out of production, aside from the technical failures mentioned in this thread. Ultimately, they didn't meet the needs & wants of players the way some other gear at that time apparently did. So they went the way of the dinosaur. Again, there are some classic vintage pieces that many people still use and rave about, but there are hundreds of designs that were failed concepts, can't hold a candle to modern-day offerings, or both.

Well you Mo Frapies, Isovent ReWiring Job complete.
The F Bomb is gone.
My friend used two Switch Jacks, which means the second way was used, which means if I plug an amp into either of the jacks, this places the Isovent into Full Mode, but if I plug into both jacks at the sametime, this places the Isovent into Bi-Amp Mode.
I didn't want to tell you about the Jack Switching until we were certain it was going to work.
Now Mo Frapies, what Sayeth You Now?
Let's hear it!!!
What Bovine and Squat to you have for me now?
One point, NOT only was the Crossover Removed, but they did find within the Isovent a Cap Filter, which was also Removed, and aside from the new Switch Jacking arrangement, we just straight ReWired the Isovent with No Extra Circuitry at all.
How is that!!!
Let's hear the Rubbish and Bovine now.

The real question is - was there ever an F-bomb to begin with, or was it all in your head?
35 pages of masterful trolling. I couldn't have hoped for a better conclusion.
Very Funny.
I knew youz guyz would come up with something.
Whether or NOT the F Bomb was in the Circuitry or just in my head is Immaterial, it's Gone Now, and the ReWiring is working Great.

Well, without going step by step, one component at a time, in the basically, rebuilding of the cabinet. You really at this point, don't know what was causing the problem.
What I do Know is the Problem is Gone.
If you really want to know exactly what was causing the problem, then I can send you the electronics, and you and various electronics gurus can go through it, and from there tell us all about it.
Actually my friend and I think it was either the light bulb or the coil, both of which create electromagnetic build up, and probably cause the F Bomb.
.
Good job.
No added lining to the cab?
In the same location of the room?
Same stuff in that room to vibrate?
Same strings on the bass?
Now see if you can replicate the F boom.

I know the difference between Sympathetic Vibrations and what is Truly Vibrating, so I know it will work.
Anyway I am bringing it home in a little while.
If I still have problems with it, which I doubt I will, I will stuff a Moving Blanket into it, and see how that works.
If all else fails, just gut the IsoVent completely and hide a good speaker cabinet inside of it. Then you are using the IsoVent as you seem determined to do, but it will actually perform well. You know...the old 'two birds; one stone' trick.

Whatever. I can't believe even a single word in this entire thread.
That is Truly Funny.
Once I get home I will send you a photo of the Circuitry my friend pulled out.
Then you can tell me.
My wife and I got the Isovent in the trunk right now.
Stopped at Arby's for some Drive Thru Din Din.
NOT to rub it in.
LOL.
