NAD 7020

The 'alt scan' picture of the amp looks different to my amp, doesn't seem to have this circuit and some things are in different places, it may be of a later model. If anyone had the same problem, please reply to this message. Yes, I'm reaching to find flaws. My wife will package well with cardboard on each side to ensure safe arrival.

In those days, the secondary windings of output transformers had taps at different impedances so that optimum impedance matches could be obtained for speaker loads of 4, 8, or 16 ohms.

Very impressive and it just keeps on going. I have heard many systems and amps since i first heard this amp and nothing comes close if you like a musically definative but sweet and mellow sounding piece of kit. I am guessing this cap in backwards caused the voltage applied to a component to be reverse and its shorted. My 3020 B did a good job with bookshelf speakers but was a bit harsch in the treble region. I am impressed with the ability to handle the low ohm loads of my three way speakers.

This has been a great product. The return on investment has been extraordinary. Powers on, not tested further. A címben szereplő lemezjátszót megmentettem az enyészettől bevallom kukáztam, de még a kidobó kezéből sikerült kivennem. Apart from blowing the transistors twice ouch! In fact, my measurements of dynamic headroom were even a bit better: 4.

My setup is sufficiently transparent to show the difference between digital and analog recordings. It has given exceptional service with no problems except a noisy volume pot that I have learned to live with. I am still amazed with it. It is a sweet sounding, reliable receiver, with plenty of power in reserve. Immediately, I found the sound to be clear, warm, and forward many big steps in the right direction. If you are into vinyl, the dynamic range for the phono pre-amp is hard to beat especially for a 'receiver'.

Cheap Van Damme silver cables internal audio line-no need for jumpers in the audio line and some good speaker cables from the Motos to l601,602 and from the coils to speaker terminals. Dry solder joints can cause problems, i have changed all the electrolitic capacitors in my amplifier,and resolderd any dry solder joints,and any cold solder joints. Weakness: The major weakness is reliability in the original setup. The 7240 shines in this department. Ha bekapcsolom, akkor leesik a brumm szintje, a hasznos jel aránylag el is nyomja, de akkor is észrevehetően ott van. Its possible you may have to repeat this.

If you have any chance of get one don't doubt it. I like this receiver very much. I quickly learned to avoid this noise by reducing volume levels while tuning from one signal to another. Oxidation of the trim pot wiper connection is the usual cause of failure. Simple styling, enough power to run my Boston Acoustics T-500 and quality was not an issue.

Also, if the amp is switched into A + B four speaker mode, there is no front to back fader. If you have additional documentation please consider donating a copy to our free archive. In its alternate, 4-ohm setting, voltage is lowered but current capacity is correspondingly increased to allow driving lower impedance speakers or two pairs of speakers wired in parallel. Normally, these same speakers have required amplifiers whose power ratings were at least in the range of 60 to 75 watts. Thinking of a T-770 soon!!! As I was living in the dorms, I had to settle for the Bose 301, which paired up relatively well and also has been service for the last 10 satisfying years. It still worked fine and I gave it to a friend of mine.

Replace with good quality Nichicon, Panasonic or Nippon Chemicon - 100V types. The output is 40 watts per channel but to me they offer a lot more. Then my uncle gave me his old Tube pre-amp and power-amp kit. That would bring the total up to about 55 watts per channel. Powered on but no audio, and noticed the fuses to Bridge D805 were melted open. They are in good shape with no stains or rips. The antenna terminals are, in my opinion, both poorly labelled and poorly configured.
