Vintage 1971 Record player hifi system -Dynatron SRX-90 Lenco GL75 AR6 speakers
The Dynatron SRX-90 is my favourite Dynatron amplifier, it incorporates similar transistors used in Quad and Sugden designs of the era. It runs 4 TO-3 type output transistors and produces in excess of 45 watts per channel RMS.
