Hey Head-Fi, Have any of you successfully replaced a laser pickup in a Marantz SA-14? The old laser won't read any discs. I already performed the standard troubleshooting, like cleaning and lubrication. With this being a newer vintage item, many of the old school POT adjustments are replaced...

Anybody know anything about this CDP? Late 80's vintage with what appears to be similar build quality to that of a Pioneer PD-91. There's a listing on ebay, but it's broken. I would buy it and fix it, but I cannot justify the cost for another CDP at this time. If someone buys it, let me...

Made the rounds at the usual thrift shops, this low-mid-fi cdp caught my eye with a price tag of $9. Turned out the pickup lens had popped off (common with Pioneers). Glued it back on, made a few adjustments, and had her singing in under an hour. This unit uses a six disc magazine style...

I'm not sure how to classify this one. It's neither portable, nor "full sized" yet somewhere in between. A little DIY as well. With that said, does anyone know the story on this amp? I did some searches, but did not find anything on it. I have no idea how long this thing has been around. I...

Greetings my fellow techies. Some of you may be familiar with this old workhorse. I picked up this broken scope for next to nothing many months ago. Only now have I had the time to look at it on the bench. It was not drawing a vertical trace and the sweep was noisy. Starting with the power...

Our third and final child was born on Tuesday of this week. She decided to come very early at just 30 weeks, but she is doing just fine in the NICU. My wife had severe preeclampsia, so the doc said it was time to deliver. Everyone say hello to Kyla! Paul

I was given a broken 46" Plasma TV by a coworker. I have isolated the problem to the "X-Scan" or "X-Sustainer" board. Some of the MOSFETS have blown, destroying part of the driver circuit. I believe I have located all of the failed components, but would like advice on other areas to check...

Who will do the safest, most thorough cleaning? It's time to get my ears squeaky clean. I have wax packed in that is causing mild Tinnitus and it's very annoying! I did a few searches and did not come up with useful results. Thanks! ~Z

So, I was doing my routine Friday thrift-store shopping and this sucker stuck out like a sore thumb. It had a "broken you fix it" sticker on it along with the $15 price tag. The unit powers up fine and the drawer opens, but it will not spin the disk, nor do I hear any other servos operating. I...

Just picked up a pair of these the other day. Sound is great, comfort is not so great. Could someone recommend compatible tips that will improve the level of comfort? What is the best? Thanks! Zip

I think TI is catching on to the past and present popularity of this opamp. Here is a list of the suggested uses: # PRECISION INSTRUMENTATION # FAST DATA ACQUISITION # DAC OUTPUT AMPLIFIER # OPTOELECTRONICS # SONAR, ULTRASOUND # HIGH-IMPEDANCE SENSOR AMPS # HIGH-PERFORMANCE AUDIO...

I swear I think I just heard my DT770s the way they were intended over the weekend (and tonight for that matter). I posted my find of the Yamaha C-80 Preamp on Saturday and spent that evening restoring it. It is mind boggling at how low these cans can go! I am spoiled rotten. This is audio...

Originally posted in the amps section and now moving here... http://www.head-fi.org/forums/showthread.php?t=257156 As stated previously, I found this rather nice pre-amp and it sounds great through the headphone jack. I thought all was well until I opened it up... Abuse!! These...

Does anyone know anything about this unit? I am trying to locate a manual or detailed specs. I found it next to a dumpster today while I was out. It's probably seen better days, but the headphone out sounds amazing! I think my other amps are going to take a back seat for a while. I'm spoiled...

Does anyone know if something like this exists? If not, where can I get the connector for a DIY solution. It appears the iPod and Sansa share a very similar connector with some of the same pinouts. A little research was done on anythingbutipod and there is an audio signal present on the Sansa...

Isn't it illegal for people to bid on their own auctions? or have friends do it for them, whom have no intent on actually purchasing the item. The seller then re-lists said item a few days or weeks later with different wording or pictures. I have no solid evidence, but in the past my gut feeling...

I find myself listening to this combination more and more. There is something to it that just sounds good, at least to my ears anyway. I think there may be some kind of synergy present if you believe that sort of thing. My current listening setup is ASIO4ALL-->Foobar2000-->Xmod (headphone...

Has anyone had issues with this cable deteriorating? The problem area lies in the straight run between the top of the coil and the driver housing. The cable gradually expands over time as if there were air inside. The consistency of the material resembles that of a rubber band. I can slice...

I know.. I know. I should probably be burned at the stake for even mentioning these cans. They were my first "real" pair of headphones before I knew better. At the time I thought they sounded very good and used them religiously for the better part of 7 years. Fast forward to today and they have...

Does anyone have experience modifying this humble little DAC? It uses the Phillips UDA1321T which is not too terrible of a chip in comparison to the BB PCM2702. You can view the datasheet here: http://www.alldatasheet.net/datashee.../UDA1321T.html It has a low voltage rail-to-rail...

Another provocative ad in the new posts section! I got some questionable looks from a few co-workers today. Great advertisement I guess, but these are starting to verge on NSFW. What's next? ****-Fi? ~ZIp

Hello All, I would like suggestions on compatible OP amps for this DAC. I have heard that an 8620 on brown dog adapter is a good choice. What about others? Dual 627s? I understand that the 2604 is at the output stage. Is the JRC considered a buffer? If so, how would stacking buffers affect...

Hello All, Is this normal or not? Is it always this way? My life is never quiet, especially with two toddlers! The other day while I was able to enjoy some silence at a friends, it was not completely silent. I noticed faint white noise that did not variate or go away. Maybe it's always been...

Would these be considered trash or half decent? My current alternative is an AR PS directional balanced line audio cable. I have some silver wire laying around and will eventually roll my own cables... when I'm not being lazy! ~Z
