“Back in Eindhoven, there where the 60’s. Radio Luxembourg on my B&O etc. I got interest in guitars and amplifiers. I built several Amps. My first amp was something with the EF11 and the EL3. I also built a copy of the Philips EL6431 Amplifier. (That’s where the output transformer of my B&O radio went) In Eindhoven there was a repair shop called ‘De Radiodokter’.
