Multiplied Transconductance Amplifiers - part 2 - high power amplification
Multiplied Transconductance Amplifiers – part 2: high power amplification Vol 8
Frank Blöhbaum always comes up with quite novel techniques to build very high performance tube amplifiers. In this 2nd part of his Multiplied Transconductance Amplifier series (part 1 appeared in L|A Vol 6) he extends his designs from a few watts to high-power amplifiers delivering over 100 watts with vanishingly low distortion. The article discusses detailed circuitry, parts selection and construction tips. No unobtainium parts are used.
