The world of hifi can be a daunting and confusing place at first, especially when looking at different models of speakers and amps and CD players and streamers and the mighty list of technical terms they come with. Hopefully, we can help bust some of that jargon here. Are we missing a word or term you'd like to know the meaning of? Leave us a comment below.
We recently installed a home cinema system for a customer where one of the existing sources was a SKY HD box. This box was to provide an HDMI feed not only to the home cinema system we installed, but also three other flat screen TV's in the home, some of which were approaching 100m away from the SKY box. In these situations, it is not possible to reliably transmit HDMI signals further than about 20m with an HDMI cable, and a different approach is required.
One of the iconic class A amplifiers of the 1980's, this amp can now be found for reasonable money on eBay and the like but may need some tender loving care. This Krell KSA50 mk2 schematic circuit diagram will help you to restore it back to it's true former glory.
This circuit information is invaluable in servicing a Valhalla circuit board - but please do take care as there are lethal voltages present. Those with experience could always 'roll their own' using veroboard or a home etched circuit board.
An excellent, reliable and good sounding amplifier from Arcam.
