2 outs to ground should be equivalent to shorting the 2 two outs together
I don't think so..... The circuit is not balanced at that point. Shorting one output to ground is more what would imagine a typical fault condition to be, ie. having a speaker cable come loose and touch the chassis. Also let me be clear that by shorting I meaning shorting a cable while music is playing. Swaping cables and speakers is a pretty common experience for us audio tweakers. I will bet money someone is going to short something at some point. The amount of alchoholic beverage disscussen on the forum also makes this seem like a pretty safe bet.
Please tell us what your PhD is in, so us simple minded engineers can stand in suitable awe. I am sure you can learn everything you need to know about EE in a couple of weekends reading though.

Fred is right . Shorting one of the outputs to the ground is a typical short with big current going through. Shorting two outputs together, what would actually happen?

This was good of you to bring up, especially when we have numbers of folks who, because of their background, may not think so carefully about these very important aspects of DIY amp design and building. Reminds me of some regulator discussions a year or so ago (elsewhere) with designs that would work fine once they started, but were not properly designed to start reliably. 😉

D%$m, all those years I wasted studying hard ... 😉
... NOT!
I hear you, Fred.

Fred,
no one cares what you "don't think" happens. At least I did more than you in proposing some starting points, I never claimed to be right.
I always found it extremely easy to proofread someone else's work.
So here is either a matter of giving you free bullets to shoot back at me or sit back and wait for granpa to show me how it's done? No thanks, I'll burn my own speakers before I do that.
Send me a private mail I'll be glad to discuss some science at large with you.

I guess you had better take a poll on that one. You still haven't
told what your PhD (piled higher and deeper) is in. I think this group needs a guru but I'm definitely not the one for it. I have an Aleph X type amp about 80% done. Where's your's gratakuitous?
If this project is so slam dunk there should be a dozen of these things going by now....
Fred
P.S. your IP indicates you are at MIT, is this correct.

While I have not contributed to the technical discussion in this thread I have enjoyed reading it, up to the point at which it appears that a personnal ******* match has erupted.
With all due repect to my electronics betters on this board it is this behavior that can tear a discussion board apart so would it be possible for everyone to put their Johnsons back in their trousers and talk audio?
Thank You.

Fred, you are no paying enough attention, I declared my major before on this site.
Took a lot of hard work to get it, I bet you had much more time to climb the lather of corporate america and rip all the benefits. Although my location sounds fancy I am still making 32K/year and still in the lab at 3am. That may explain the lack of time to read about EE stuff, the lack of money to buy a pcb and finish the X, and my frequent bad mood for which I offer my apology.
and with that I salute you. 🙂

11/12/02 pcb count....
We've lost some momentum, folks.
Two people have dropped out and it cost us 4 pcbs.
Today's count is 56 pcbs.

Where's Elmo?
Hey guys,
There's money coming my way for 18 pcbs. I want to place the order for 56 pcbs this Friday and I don't want to end up paying for all these boards myself. So, for my peace of mind, please email me and "show me the money".
Thanks,
John Inlow

So, for my peace of mind
John,
don't forget the peace of mind of the guys that paid already, too!
How about posting the list of members that didn't pay? That will maybe jolt their memory.

I'll send another private email
Grataku,
The folks who haven't paid yet probably don't realize that I want the cash assurance prior to placing the order.

Thank you, John, for taking the initiative and finding the time to do this. You are a true giver. I'm impressed enough to send some money across the border in good faith.
Paul
p.s. We're thinking of doing the Oregon coast sometime.

Hey Paul,
Thanks for the generous compliment. If you're ever out near Portland, Oregon, look me up. I've love to visit.
