Would it be impertinent to ask just what line of work Hong is in? Seems like he's someone I'd like to be friends with. :D

Re: 2x250 IRS2092 amp build

Hong also promised to install a stainless steel pole in Lowell's living room, and give him a one-year free supply of strippers if the PSU didn't work. Anyone else wants this deal?

I do. And i'll make sure that PSU doesn't work :D

Interesting....that just happens to be my price for designing custom amps with DSP that are controlled by speaker-designing software. We need to talk.

Put in in the HT last night and played the song ASA from the album ASA. The last half has some serious drums that will get a woofer going pretty good, to say the least, and it did just fine. Way louder then will ever be for a movie.
Insert big smile.

NO Robert. I just knew that it would be fine. Hong said he would go on a gameshow and win me a new car if it didn't work perfectly!
I won't really know if it is a huge improvement until I get it in the home theater. In my small room, its great.

Can you tell any difference?

I'll bet the fingers were trembling a little bit before you hit the Power Switch.....That would be normal.:D

made the changes and no magic smoke! Thanks to all!

Craig, you wouldn't qualify to work on the suicide hotline for sure.

I'm not sure if that is encouragement or discouragement :eek:

Re: 2x250 IRS2092 amp build

I don't feel too bad now after reading this Neil. I've had exploding caps, major sparks from allowing wires to touch each other, melting resistors, and too-numerous-to-count mishaps trying to understand how to put an amp together. Thanks for the encouragement, the guidance, and taking time to answer our noobish questions.

You did a good job on the chassis. I'm glad to see more people getting involved in amp-building.

The grounding is always the most mysterious part of amp-building, especially when you make your own boards. Many years ago I built a six-channel amp that oscillated and fried the outputs whenever I turned it on. By the time I separated out all of the grounds and got the amp stable, I was no longer interested in working on it. Also, I had used power-hungry TTL logic for front panel touch switches and needed to redesign too much to use those new CMOS devices, so I moved on...

I've always been afraid of electricity--I always dread that first flick of the switch. Too many exploding parts over the years :eek:. The worst scare was when I was debugging that six-channel amp with an oscilloscope. It used a triac/zero-crossing circuit to turn on and off the power, and it never occurred to me that putting a scope ground probe on the AC line wasn't a good idea. It actually vaporized the scope probe ground wire. I know it takes some nerve and guts to work on amps, so I admire your desire to work on this stuff.

Keep it up and don't get frustrated--it's a fun hobby with good rewards.
