Default Re: Grundig A 7400 (CUC220)

I was just about to mention the Doctor Who connection!
Most of these had the Hitachi CRT which just goes on and on giving a crisp picture. The odd capacitor failure, tuner dry joints, the power supply failing due to the resistor mentioned and the tripler are really all I can remember and I serviced loads of these. ISTR you needed the exact tripler or else the A1s were wrong.
I think this was the first Grundig to change from the thyristor line stage following the GSC100 and marked a significant improvement in reliability. The budget CUC95 (small vertical chassis) was a good performer too.
The later G1000 wasn't great, but it wasn't really a Grundig at all.
