Re: Grundig A 7400 (CUC220)
From the top of my head it would be some variant of the BG1897. It should be on the schematic, possibly dependant on the picture tube used. I haven't seen defective triplers that often. Grundig became well known for them,though, when they switched to the BG2077/BG2087. Pure garbage. Only HSE managed to make reliable generic replacements. At some very late point Grundig used BG2032 or BG2034 replacements, I think.
