    Yamaha M-50 capacitor rebuild.....

    Some problems that ended in a complete rebuild of the M-50. Only issue now that all small caps and transistors are replaced, what power caps to use. 10000 uf X 63 V @ 105V. May as well do all 4. Just did a rebuild 5 years ago and ONE power cap is bulged. Range is low ( 9850+- ) but ESR is double...

    Going crazy with my Yammy C-50 M-50 combo.

    Severe distortion on startup and doing my darnnnest to figure what is giving the issue. Sounds easy huh. I have cooled and restarted both the pre and power many times. And sorry if I did something wrong but I have not been able to find which one is the culprit. Takes around 20 minutes to clear...

    C-50 Phono 1 vs Phono 2 switch

    I finally came up with a logical solution that has been bugging me for the past 6 years. That being the failure of the Phono 1 vs Phono 2 selector switch. The actual slider is not larger that the head of a pin and is totally open to the outside environment. Really this switch is so small and...

    New tweeters for my L-100's.........

    After I found one of my L-100 tweeters blown around 5 years ago I have been putting off the fix. I finally found a pair of bullet nose titanium/aluminum tweeters. Very 075'ish in my thinking. I found them on sale for $30.00 for the pair free shipping. Delivery went quick. They are heavy. almost...

    Deoxit miracle.....

    I have a setup of 2 Yamaha C-50 preamps. Of course Yamaha is known for having issues with poor contacts, dirty relays and others on the magnetic preamp areas. I tried a Deoxit solution of a ounce of denatured alcohol with 10 drops of Deoxit red. It was a miracle. All the dropouts, distortion...

    How about some LP cleaning that sounds great.......

    I have been experimenting a long time. It seemed to me that.... LP's sound better when cleaned by.... 1. Spinning my TT at a greater speed than printed on the LP. My old Sony LX-300H is at 49.5 RPM max. Checked with my iphone running the "RPM" app. 2. Using a stiff stylus like my...

    Dull coating on LP's????

    I got some Lp's last week and a few have what I call a very dull coating covering both sides of the LP. It looks to me like a glue or varnish. I don't know what the purpose of this stuff is. I played after cleaning and the LP sound absolutely perfect despite the date on the jacket being 1958. I...

    AT toss up....

    I saw the listings for AT needles quite confusing. AT made (ATN3472C) is listed as a elliptical shape on several sites. The assigned needle for my cart is ATN3474C(non elliptical). But another listing says it should cost around $25. But the listing for the elliptical in one case is listed for...

    Audio is in me....

    Very interesting editorial in latest "Stereophile" page 3 of the Dec. 17 issue, commenting on what is it we are doing here. Robert Schryer comments on our obsession. Audio is in our blood and part of our makeup. It controls all we do and how we think. That amp, speaker, TT, tape deck, and the...

    3D glasses charging cable......

    We got our 3D glasses many years ago but due to little interest and rare 3D movie showing we never used the glasses. Now lately 3D seems more popular. However we attempted to use our glasses only to find that they are not charged. Searching through the boxes and packages we never opened failed...

    Yamaha blown????

    My C-50 preamp is not working right. Earphone jack works ok. Amp powers up fine. Clicks as it should on start up. However there is little to no output at main outputs. I can faintly hear something and it is all distorted. Something disconnected by accident last week that created a monumental...

    Yamaha front push button inserts

    My Yamaha KX 1200U has several missing front push button inserts missing. Came that way when I bought it around 8 years ago. Looks like crap without the insert. See photos. Any suggestions would help. I could make new but would like new/used same as if possible. They are die cast aluminum. Only...

    Yamaha cassette tape rubber wheel source.

    I need a new small drive wheel that drives either the take up wheel depending on what side is taking up. It flips magically to either side when activated. The outside dia. is .550" dia. The inside dia. is around .390 The thickness is .085" and the cross section is almost square. It is used on my...

    What do you want? Dish or DirecTV???

    After wrangling with Dish for several months we finally pulled the plug and changed over to DirecTV group plan. The new DirecTV will only be good for 2 years with I am sure hefty increases after. But it will save us over $100/mo for the package plan compared to a similar package plan from Dish...

    Getting ready to replace the tweeters in my L-100's....

    I have read and read about replacing tweeters in my L-100 's for several years now but I am getting ready to take action. The only problem is that I have gotten so much contradictory info. about either adding new design tweeters or sticking with the same old style tweeters. Cost will play a part...
