The Linsley - Hood single Ended Solid State Class A Amp In one of the recent Electronic & Wireless World's there was a updated Version of the Linsley - Hood single Ended Solid State Class A Amp. The major part of the re-design was the removal of the Output Capacitors. The Author build the original Version in the early 70's as replacement (stereo) for his Willamson Amplifier. Spec's where 10Watt into 8 Ohm. The Author claims that his Amp was up against his Wiliamson Valve Amp and a ST70 and sounded MUCH better than the available Transistor designs of his time. The re-designed Version uses stabilised +/- 22 Volt Rails, 2 Ampere Bias Current and two npn BJT's in the Output (the hepepitaxial version of the 2N3055 - this is not the 3055 we all have come to love inside our first homebuild Amp!). This Amp has some global feedback (so has the Pass-Zen) and should put out 15 Watt into 8 Ohm. some of my own calculations suggest that with +/- 16 Volt Rails and 3 Ampere Bias current we should have a nice Amp for the Poly Natalia or the Ariel (as far as solid state designs go under Nice :) ) with 15 Watt SE power into 4 Ohm (Power Dissipation would be a whopping 100 Watt per channel.
