    C-90 and M-90 electrolytic capacitor list

    If someone already made out a capacitor list for both the C-90 and M-90 and is willing to share I would be extremely grateful. I am looking to re-cap both in the near future and having the list would save me an immense amount of time.

    Another Sony SCD C222ES issue

    So I replaced the belts and got the drawer working properly and now I have a new issue. When I first turn the unit on, it recognizes a SACD. After 15 minutes or so of being on, it has a difficult time doing so. Sometimes it recognizes the SACD and other times it says it's a regular cd. I've...

    Sony C222ES carousel drawer issue

    I replaced both the carousel belt and the drawer belt on this unit as the drawer belt was slipping causing the disc not to load (thanks Sony for not providing a removable bottom cover). I now have a new issue though not serious. When you go to load a cd, the drawer wants to close but gets hung...

    A-77X micro switches

    Anyone know of a Digikey or Mouser replacement for the A-77X micro switches? I've grown tired of cleaning the darn things... they last for a year or so and then act up again. I noticed a slight hum from the speakers that didn't increase with volume and discovered it was caused by the line...

    If you own a pair of JBL L100's

    with the original crossovers, try this: The cross pieces were made from wooden skewers and there is a custom grill that press fits into the frame. You'll be amazed at the sound you were missing.

    Pioneer service manuals

    I just happened to come across this seller on eBay when searching for an original M-90 service manual. http://stores.ebay.com/macaddict6 I have no affiliation with him though I am a happy customer. He has many Pioneer manuals that some of you may be interested in at very reasonable prices...

    Kent would be pleased

    I won a DBX 224 type II noise reduction unit on eBay for $6.50. I was fortunate as the unit was described as untested though it did power up. I found some broken solder joints on the RCA connectors and of course the switches needed cleaning. But it works and sounds much better than the built-in...

    LPR35 and an Akai GX747-DBX

    Gosh, compared to SM911, LPR35 gave me fits when trying to calibrate the deck... it's definitely lower output. When I was done, recordings sounded nice and I now have the ability to record 3 hours at 7.5ips. :)

    cd, sacd review site question

    Does anyone know of a website that offers reviews of CDs and SACDs based on audio quality? I am looking for a SACD of Schumann's Symphony #1 and although I have quite a few choices I have little way of knowing the quality of the sound recording. The quality of the performance is important as...

    Asking for help, advice on circuit board repair

    I purchased a DBX 3BX Series II expander a few days ago. It's in remarkable physical condition without a mark on it and it works beautifully on classical FM broadcasts. I removed the cover to use Deoxit on a few noisy switches and upon further inspection I discovered this: The crack in...

    Would like recommendation for am antenna

    My recent purchase, a Pioneer F-91 tuner, doesn't have a built in am antenna. Can anyone recommend a loop antenna? Grundig makes one as well as Terk though I'm wondering if the generic loop antenna that came with the more recent tuners is just as good or better. Any advice would be appreciated.

    DIY FM Antenna

    I recently purchased a Pioneer F-91 tuner to go along with my C90/M90. We always had poor reception as we live in a valley between two rather large hills in the Berkshires of Massachusetts. So I started off playing with a RadioShack model #15-1833 indoor powered FM antenna that I had lying...

    F-91 tuner added to collection

    Just received a Pioneer F-91 tuner in today's mail purchased off of eBay (top component in picture). Beautiful condition and it completes the C-90/M-90 setup. The sound is wonderful as well. Now I'll need to pick up a good quality, small sized fm antenna to set up in the upstairs crawl space. If...

    How to flatten rippled tape

    I just purchased The Glorious Sound of Christmas - The Philadelphia Orchestra - Eugene Ormandy Conductor off of eBay. Beautiful sounding for something 52 years old. It looks as if it has never been played having the end of the tape secured to the plastic reel with a circular sticker. The tape...

    Mark and bad solder joints

    Mark's consistent advice to first check for bad solder joints when there are issues is starting to haunt me. :) I've been dealing with an annoying though not serious problem with a Pioneer A-77X integrated amp. Whenever the weather gets humid, the amp takes 5 minutes or more to come out of...

    Is the A-77x's volume control servicable?

    I just finished re-capping an A-77X (everything but the function assembly board which seems to have four electrolytics in the eq section). What I noticed during testing is that if I turn the volume control quickly in either direction I get static in the left channel. If I move it slowly in...

    Remote for Akai GX-747DBX

    As anyone of you who owns an Akai GX-747 knows, the original Akai remote for the GX-747 is near impossible to find and if you do find one, you can bet it will be priced into the stratosphere. I came across a Panasonic SSE44 DAT remote pictured below that works like a charm. It has an eight pin...

    Need help locating a direct plug-in transformer

    I know this isn't audio related unless one thinks I light up my stereo rack with a Solux halogen lamp. :) We recently had a close lightning strike to our home that took out our well pump, numerous bulbs throughout the house, a cordless phone and tripped four circuit breakers. Luckily none of...

    Energy Concepts Function Generator

    I purchased one of these a few days ago. I was wondering if anyone had a service manual for it that they could share as a pdf file. It's working ok though could use a calibration. The company is still in existence making bench equipment for schools though being a cheap bast*rd, I'm reluctant to...
