Weird. I thought I had it set to email me, but I guess I didn't. Sorry for not responding, I figured no one had any subs to sell and never checked in here. I'll send out emails for the ones which look interesting.

You know, those things that come with HTiBs and have 8" drivers and shouldn't even be called subwoofers and are the first things to be upgraded/replaced? Anyone have one of those lying around?

You could use John Pomann's kit, I would think. It's a good basic starting point, and you can make it fancier as you go along (better opamps, more complex circuits). The Linkwitz Lab website has schematics for a bunch of circuits that you may or may not need. For instance, if you need/decide to...

Sold.

Hi, I'm putting my turntable up for sale. I finally upgraded to a better and more expensive turntable after about 3 years - this has been the component that's stayed in my system the longest as I went through upgrades for every other component. This was my first 'real' turntable (not counting...

They have better transient response. I checked it out on my scope once and posted the info on HTT and AA. The thread on AA of course got a little heated, but I think my basic tests were mostly sound. I could try and dig up the thread(s) if you're interested. Edit: Here it is, even if...

Figure out which driver needs to be attenuated, and then put potentiometers on it. You can leave it that way, or once you've picked a final position for the pot, measure it and then use fixed resistors to build an equivalent voltage divider. That's what I planned to do, but I'm still playing...

I guess it re-clocks the input data?

K & K Audio have a DAC kit that's been getting a fair amount of buzz on their forum (on Audio Asylum). I bought the Ack dAck non-oversampling DAC - not offered as a kit any more, but I'm very happy with it. But NOS DACs are a pretty fringe product, most people seem to love them or hate them.

TT: See if you can score a Pioneer PL-12D off of eBay. I bought mine for $25, and paid another $25 in shipping. You should be able to find it for under $100. People tell me it's an overachiever in its price range. If you get lucky, you might find a Dual or Garrard or maybe even a Thorens...

I'm not doubting the your husband's capabilities :) A voltmeter will be able to tell you if a resistor is bad. But if you've fried transistors or chips or anything like that, it becomes pretty difficult to troubleshoot those - figuring out which component is bad, where to get a replacement part...

For resistors, ALWAYS get a wattage rating that's equal to or larger than what was originally on the board. Never go with a smaller wattage than the original part. Think about it this way - the original part was able to handle 0.5W. Let's say it had enough current going through it that it was...

OK, looks like we're all in agreement here, more or less :)

Well, it's good to see you again. I know exactly what you mean about having fun conversations vs. the usual stuff you see on most forums. This is definitely a good board for learning about HT stuff.

But what are some of the benefits of passive crossovers over active, other than cost and number of amplification channels? Or, let's put it another way - what can be done with a passive XO that cannot be done with an active XO? The only thing I can think of is a series XO, and even that might be...
