Digital-Analog-Converter for audio application for Roland E-PianosPCM56P von Texas InstrumentsThis part is used from RolandRoland part number:15209122 Resolution: 16bitInterface: seriellConversion rate: 666kS/sNumber of DAC outputs: 2Number of channels: 1Case: DIP16warm-up time: 1 minMechanical Description:The digital to analog converter is housed in a DIP 16 package and is designed for classic through hole mounting on a circuit board. Use of a socket is possible. The DA converter has 2 x 8 connecting pins with grid of 2.54 mm x 7.62 mm.Technical Description:This D/A converter was developed specifically for use in audio applications. The DA converter provides low distortion and typical differential linearity error is 0.001%. The interface is serial and provides a 16 bit resolution. The conversion rate is 666kS / s. For operation, no external components, such as temperature compensation or similar is required.It is a symmetrical supply voltage of +- 5V to +- 12V needed.
Rotary potentiometer for LCD Contrast adjustment The potentiometer is firmly soldered to a circuit board. For replacing the button craftsmanship and experience in soldering is required.
1 pcs. Rotary Potentiometer new for Modulation 2 suitable forYamaha SY99 Modulation 2Resistance: 10 KOhm
1 pcs. Volume Slide potentiometer with 30mm travel. Suitable forYamaha SY77Yamaha SY99------- Out of Production --------Electrical properties:The stereo nominal resistance has 10 kOhm, the electric resistance gradient is logarithmic. The potentiometer is construed for a power of 0,06 Watt.Appearance (technical characterisation):This slide potentiometer has been built in in the past in many instruments and audio equipements. The particular embodiment of this potentiometer is the arrangement of the solder contact pins, which today are no longer usual. In total eight solder contact pins are laterally ordered to a group of four pins at the top and the end of the slide potentiometer. On both sides the solder pins are staggered in reverse order. Because of this arrangement the volume control fits only in a specific mounting position. The slide potentiometer has a travel of 30 mm.In medium range of the casing the metallic edge-socket connector is mounted. By these connectors the slide potentiometer will be fixed mechanically.Useful hint:The volume control is soldered on the circuit board. You should have mechanical skills and experience in soldering to replace it.

Yamaha SY77 Synthesizer
The YAMAHA SY77 is the predecessor of the YAMAHA SY99, which was released two years later in 1989. Both, the SY77, and the SY99 are quasi direct successors of the YAMAHA DX7, probably the most famous synthesizer of the 80s.
The SY77 was designed by Yamaha with the intention of combining classic FM synthesis with the ability to use sampled sounds.
It was intended to provide improved access to sound generation by users who had previously found it somewhat difficult to use the purely FM synthesis based DX7. To some extent at least, this plan was also successful, if some elements of FM synthesis were replaced by AWM elements.
With, or without keys?
Like many other devices, Yamaha also offered the SY77 in a pure rack version as TG77 starting in 1990. The rack version has, among other things, an additional 8 individual outputs and a larger, more readable display, but does without the sequencer present in the SY77.
The device was delivered, differently than rack versions of other manufacturers in generous 3 height units, but unfortunately the menu guidance had not substantially improved for it.
The sound of the SY77 and also of the TG77 can probably be called fat, at least recognizably from the sounds of other devices of the competitors.
Need a repair?
The most common defect of the SY and TG series today is probably the display.
After 30 years of life, the readability of the displays has deteriorated considerably. Another very common error in relation to the displays is the strong, very high whistling sound that comes from the power supply of the display backlight.
We offer replacement displays in our online store that are 100% compatible with the originally installed ones.
These can be purchased for relatively easy do-it-yourself installation. For those customers who do not dare to do the installation themselves, or those who do not want to make the effort to do the conversion themselves, we offer of course the conversion in our workshop.
Here we also have all the necessary measuring instruments and tools to repair other faults, such as loose contacts on the jack sockets, scratching of the rotary and sliding potentiometers, as well as bouncing of the buttons, at the same time as changing the display.
Make an appointment with our workshop for the delivery or sending in of your TG77, or SY77.
