With a DPDT swich, the center is usually "off", and each of the other two postitons is "on" (on-off-on).

I don't have the link, sorry. It has been my experience that the best way to cure a warp is not to. Those that have formed by improper storage will correct themselves over time if the record is stored properly -- vertically, not leaning, with mild, equal pressure on both sides. Those...

Assuming the AC adapter for the headphone amp doesn't have a polarized plug, I'd try reversing its orientation to see if it makes any difference. I'd do the same with the powered speakers if possible.

Parts Express sells several different types of solder containing lead.

A double-pole, double throw switch should fit the bill perfectly. Its common terminals get connected to the preamp's output, and one set of the remaining terminals goes to the headphone amp; the other to the power amp. The grounds are all tied together.

Sirius and XM use proprietary systems, so you have to use their radios, and find those with digital outputs... I remember seeing one for XM, and one or two for Sirius. From there, it's a standard DAC, no different from any other. I've not heard much of XM, but I have Sirius. They use so much...

For a home amp, the CKKIII is the way to go. It's easy to build, fits the price range you mention, uses parts that are easy to find, and, of course, sounds great.

I just happened to perform this adjustment recently, and here's how I did it... First, I bought a test tape. There are plenty of places that sell them; I got mine from Studio Sound Electronics. These tapes contain several test tones, including one that's meant for speed adjustment. Mine uses...

For attaching circuit boards to plastic cases, I use threaded nylon spacers and nylon screws. I believe Mouser has a nice selection of sizes. I glue the spacers to the case, using a super-glue/crazy-glue kind of stuff (can't remember the generic term). Just make sure it's compatible with the...

There's also Ramsey... http://www.ramseyelectronics.com/ They have pretty good instruction manuals... not like Heathkit, but the best I've seen recently.

I don't see anything wrong with this... it's the same as if the two transformers were plugged in separately. Make sure you choose the correct fuse for each, and that your power cord can handle their combined load, and you should be fine.

I'm not exactly sure what you mean by flatter/lower... Do you mean the high-frequency sounds are missing/muted? If so, this could be misalignent of the head(s), or it could just be the tape's optimal bias is different from that for which the deck is adjusted. Have you tried different brands...

A small reamer is handy, too. It lets you fine-tune the sizes of round holes. This can be important, because it's tough to have every size bit you need. Just choose the next smaller size, and enlarge as need with the reamer. And speaking of college... I still use the same reamer I bought while I...

I can personally attest to the fact that the CKKIII and HD-595s make a great combination!

I just built a CKKIII... one of the nicest amps I've heard. Quite economical, too -- but you'd never guess this by listening. What I like best is its uncolored sound. Highs sparkle without being shrill or harsh, and lows are solid and well-defined, not muddy or booming.

It's some kind of multimeter, oscilloscope, or similar tool. I did some checking on the Internet Wayback Machine, and was able to get the first pages of the "test and measurement" section categories to come up (the August 15, 2000 version). Everything on the pages is similarly numbered, but the...

That's exactly how I've always done it, and it seems to work fine. If you're so inclined, you can pass the left and right signals over the terminals of an SPST switch. Switch open = stereo, switch closed = mono.
