QUAD II amplifier serial dates

[Strange Brew]

Hello all.

Does anyone know if you can date the Quad ii amplifiers using the serial numbers?

Cheers

All vintage Quad II used the same component and same brand. Just becareful the badge is changable. I do notice different types of cable sleeves used compare to early and later manufacturing. Ie, Serial 2000 vs 20,000. Propably you can check with Quad for detail.

I believe early ones had both 4mm speaker sockets black, later production had a red and a black.
