Interesting stuff! Always thought the Grundig 5010/6010 were excellent sets - the thyristor LOP stages did not give much trouble. The main problem was that engineers did not understand how they worked. But there again, some struggled with figuring out a PL81/PY81
Only worked on the hybrid Kortings - again, excellent sets, and very reliable. They used a ladder-network RC oscillator for ident, locked to the burst-derived 7.8khz.
Teleton - I remember the hybrids with the weird valves, and touch buttons that were oscillators that stopped when you touched the buttons, unlike the Grundig that amplified the mains hum from your finger.
Only French sets we saw were Emo, with EL509 and EY500.
