A demonstration of a home-made AM broadcast receiver. The set uses two transistors (MPF102 FET & BC548 NPN) and one audio IC (TDA 2822). The test was done in the middle of the day with no external antenna. If done at night many interstate stations would have been heard. The circuit of an earlier version (without the IC audio amp) appears here: www.alphalink.com.au

Whole Home Audio Demonstration + Setup Overview

Whole Home Audio Demonstration + Setup Overview Tube. Duration : 14.78 Mins.
Timeline: - 0:00 - 10:20 The demonstration - 10:30 - 14:47 The setup In this video, I demonstrate the whole home audio system I've setup in my house. The system is powered by Apple's Airplay technology and uses the Airport Express router to wirelessly stream content from devices to the receiver. If your house has already been framed yet you wish to add a Whole Home Audio System, I would suggest looking at the NuVo Renovia: www.youtube.com (It is quite pricey!) Other manufacturers of Whole Home Audio Systems include: - Nuvo: www.nuvotechnologies.com/ - HTD: www.htd.com - Sonos: www.sonos.com If you have any questions, please feel free to leave them below! - www.ravall.com

Technics SA-560 Repair and Demonstration

Technics SA-560 Repair and Demonstration Video Clips. Duration : 10.57 Mins.
Please read this whole description. No less than four attempts at uploading later, here's the Technics SA-560 stereo receiver. It was also marketed as the SA-956 (different color, same thing). This model appeared in 1985, only about a year after stereo television broadcasting was formally introduced. There are a few things that make this unit unique. Although it is limited to the VHF band, the first is a built in audio only TV tuner that can play back monophonic, MTS stereo or secondary audio program (SAP) broadcasts. Analog TV is obsolete, but an RF modulator with stereo output can still allow you to use the TV tuner, as demonstrated in this video. Although there is a "CATV" band on the tuner, it is limited to tuning channels 2, 3 and 4. I'm not sure how it is really intended to be used. It seems that using it with an outboard cable box would restrict you to monophonic sound as most devices featuring an RF modulator do not put out stereo audio in the RF signal. (There are few exceptions to this.) Television audio appears to be run through a dbx noise reduction process as indicated on the front panel. A special vacuum fluorescent front panel display alternatively indicates power output or activation of the stereo "expander" function. It's really not necessarily but at least it looks "cool". And you wouldn't see anything like it on a modern receiver! With its VCR input (shared with one of the tape monitor inputs) and special audio equalization option, this could be seen as ...
