These tubes were made more than half a century ago, and they have an S in the suffix. At that time it meant a lot more than it does today, today suffixes are just a marketing trick. It used to mean a lot more - careful testing and selecting from huge batches and checking of many parameters. That's exactly why I don't accept any returns. Returns are simply not possible. If Telefunken is behind those tubes marked with an S and sealed with a red tape, I can offer nothing more in terms of warranty.
As is, what you see is what you get. No returns please.
