After living with this radio for a while, I have one issue which needs resolving. It seems to have a bit of an issue with the letter S, it almost slurs it. It's a subtle effect but it would be nice to see it gone. A full alignment didn't help with this issue. All the tubes are good.

I made a video to capture the issue. Almost seems like poor audio bandwidth?

Does it have a tone control? If not, you might try a treble-cut capacitor across the output xfmr primary. Try various values around .001 to .01 so.

Simple tone controls were usually a treble-cut cap in series with a potentiometer or switch.

Hi, thanks for responding.

It has a really cool three position tone control - treble cut (cap like you suggest, sounds muffled) - flat - treble boost. I tend to use flat, treble cut is a little harsh, it spoils the highs.

I tried listening to the same thing on a 1938 silvertone and it sounds very similar. Could just be what CBC is doing to their signal.
