A matching Yamaha T-760 tuner. It sounds (and obviously looks) great with the A-760. The cost was 6 euros, plus 16, 20 euros for shipping from Austria. 31-12-2006: Put back an X2 RFI capacitor, cleaned all the switches and pots with De-Oxit, re-checked and readjusted bias and offset and power supply voltages per the service manual, visually re-inspected the circuitry, and now it`s

setup for some serious listening with a pair of Yamaha Pianocraft bookshelves. So far performing (and almost looking) like new! 24-12-2006: Replaced a burned lamp with a couple of resistors, a diode and a white LED. Checked the power transistors, cleaned up the amp, fired it up and it works! 23-12-2006: Opened the cover, found out what was burned, took some pictures. See below. A quick visual check of the other components does not reveal any obvious damage. 23-12-2006: got the amplifier this morning, directly from the previous owner, with the original owner`s manual. Was warned about the smoke that came out of the amp when it burned. It does smell bad! The Yamaha A-760 is a stereo 80W/ch. integrated amplifier manufactured in Japan by Yamaha and sold worldwide only in 1981. I have the European model. The A-760 and its slightly bigger brother (100W/ch. ) the A-960 are the successors to the renowned CA-1000/CA-1010/CA-2010 integrated amplifiers. Yamaha advertised the A-760 and A-960 as featuring a new "X" power supply, which would adjust the power supply`s line voltage to the level required by the output stage; Yamaha used the same technology in their R-1000 and R-2000 receivers, and in the TOTL M-60 and B-6 ("pyramid" design) power amplifiers. Apparently Bob Carver held a patent for exactly this sort of technology and threatened Yamaha with a patent infringement lawsuit. In 1982 Yamaha came out with revised A-760II and...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
