Tom Brennan makes a good point if the reason you have the equipment is to listen to music. If you have the equipment because you collect equipment, that's a different thing. Personally, I'm in it for the music, but to each his own!
I believe the channels are 10 khz wide on AM, so AM mono, in addition to being noisier, has less bandwidth than FM. I can't see how AM stereo would be better than FM stereo
You might run both twin lead and coax from your attic to your receiver. It would be an interesting experiment, if nothing else. The coax, plugged into the right input on the receiver and a balun on the antenna end, has the potential for being quieter. I have an old Radio Shack TV/FM room...
New and vintage systems listed below. The major difference in sound is due to the speakers, I know, because I have run both speakers on the new system. I'm not sure about proud, but I am happy with both.
Use basic RCA cables for everything but speaker cables. Use lamp cord for speaker cables, choosing the gauge based on the length of the speaker cables. A buck a foot for the speaker cables and 10 bucks apiece for RCA cables.. Ballpark a hundred bucks. Divide by the price of your equipment to...
I think a capacitor will squelch oscillations, although I haven't tried it. I've attached a document from a British company that restores amps that used the old-style RCA hometaxial devices which explains things pretty clearly. I saw the same oscillations in my AR AU after, unfortunately...
I would use a variac to turn up the power for the first time, then follow the instructions if it goes to full power without high-frequency oscillations. I've seen them on an oscilloscope at around 100kHz, they are bad for the transistors and could be bad for your tweeters.
You will almost...
I think this is the best first position to try. The 3s, like my 3as, do not put the three drivers on a straight line. When used as bookshelf speakers with the AR label on the lower left, the tweeters are on the upper right. That's how I have mine. Saying all this, putting both tweeters on...
I received an assortment that included a lot of higher-voltage caps, and soldered one into the defective board. I hooked up an AC signal from a variac to "AC IN" on the upper left. It took a little work to figure out that I needed a DC voltage on the pins marked "SIN" on the lower right to get...
I fixed our drier with a little more effort--one of the rollers was defective. A few bucks for the part, but the tear-down and re-assembly took a very long time--it required almost complete disassembly. Fortunately I found a video online for the same model drier, otherwise I think I would have...
I went back and forth about buying the board, finally got it because it was relatively cheap. Today I ordered a set of higher-voltage caps to repair the old board and do later repairs as necessary. There is another board in the hood which powers the motor which is much more expensive, if it...
You spotted the weakest link, I believe. I've found that the music I listen too (mostly classical) benefits from the good aspects of digital, so mostly my source is CDs or CDs converted to flac that I've uploaded to the cloud. The turntable is mostly for when I get nostalgic and pull out an...
A while ago the task lights on my kitchen hood started blinking when they were set on high--strangely, only on one side. After determining that the bulbs were good, I found the power supply for the bulbs, and noticed that it contained a dreaded bulging capacitor. I was able to find the entire...
What is the scale on the time axis? If it is oscillating at 1.57 megahertz, each time unit would be half a microsecond?
I'm tempted to say that you are getting positive feedback at that frequency, but it is a pretty high frequency.
Here's how a true audiophile decides: Consider two rooms. One costs the average price of a room in a US house, $99,000. (Based on a US average house price of $495,000 and an average number of rooms of about 5. ) The other room has a price of $1,000,000. (Imagine it is in a very expensive...
