Did the power caps with 1200uf Nichicons and was feeling brave so I tried the coupling caps.  Man those buggers are hard to get off.  I tore off a pad!  The trace leading to the pad lifted though - I scraped it gently, tinned it then soldered the positive leg of the new cap to it.  With a...

Not worried about death by amplifier. Everyone goes sometime and driving to work is dangerous too! The depth of a project like this also doesn't scare me. Patience is a powerful force. I looked at doing an AMB headphone amp a few months back, but school made it an impossibility. I'll likely do...

Aw man, I'm in the DIY area, why are you encouraging me to get out? :-) That plate amp is too scary. "Just add sub." Gotta do more legwork if I'm going to call it a diy project!

I'm not 100% married to the 50a idea. It's what would be needed if I were to use my existing 12v amp though. 400-600 watts is not so astronomical for a subwoofer, but 50a admittedly is a lot of current in a domestic setting. I was actually thinking about nixing this whole idea in favor of an...

The sub is DVC at 4 ohm per. I'll probably run it at 8 ohm. If a higher voltage amp is reasonable to build, and will sufficiently drive a sub like this, I would be thrilled to do that instead. I find a lot more information on more general purpose amps than monaural subwoofer drivers. Needs a...

No worries man, it still contributed! I might wind up pursuing a battery route, but it might be too expensive, considering that I would need very specific enclosures and a sealed battery in addition to a charger. Plus I want to make something with the Hakko I'm getting soon :-)

Tomb, I was looking around and the lm317 circuit can be used as a regulator, but probably isn't the best to get up to 5-700VA. Thinking I'll probably have a lot of parallel components to reach the power goal. I really appreciate your input! There isn't an ac-dc ripple in the same way, but old...

I knew that was coming. :-) The goal isn't really to ghetto rig it up. I might do the battery thing just to proof-of-concept it, but it's not a permanent solution. It would be perfect for the garage though...

So I've been in need of a project for a while, and my pocketbook isn't going to allow me to just start buying cool components and making an ideal setup.  That said, it is easy to "nickel and dime" my way (my wife ) into something workable.   In case the voltage and amperage in the title didn't...

Yeah, unfortunately I failed to read your review before the purchase.  As you can read, he did similar to me:  Gave me negative feedback because I was unsatisfied with broken headphones...  It's really unfortunate.  I was hoping to find a moderator or admin who might be willing to clear my good...

Perhaps an odd request, but I'm looking for a Headphoneus Supremus in the Spokane/Coeur d' Alene area to help settle a dispute over a bum set of headphones I unfortunately purchased.  This is the classified:  ...

This is the classified.  I thought it odd as well, but yeah.  Should have bought new I guess!  If you can think of anything to try (nondestructive of course) I'd love to hear it...

Thanks for the reply, Katun!  I was only trying to be very clear...  I am happy to restructure it to be less confusing/intimidating.  I work in software QA and this is the form that we use for clarity and comprehension in bug reports.  It's the best way I know how to present an issue with...

Come folks, help save me from RMA!  They're taking their dear sweet time getting back to me about it, so I'm pursuing a "natural cure" in the mean-time.   Bump2 - Electric Boogaloo.
