Those early transistor sets are getting like tube radios now, if you want one to work properly change the condensers first, some won't work at all unless you do.

Thanks OlegKostoglatov

Yep, exactly

There is no such thing as a "biasing capacitor" or a capacitor that is biasing. Leaking capacitors can certainly change the bias however.Leaving a bad capacitor in circuit is a very bad example.

Go back to the books and study some more. True it is a bad practice to leave old caps in. I left them in so that I would not lose them. It is not a customers radio.

your royal had the same squeal problem as my royal 500H before its caps were replaced.

This is interesting. I have an old transistor radio, made to look like a Sinclair gas pump. It doesn't work at all, and I don't have the equipment to fix it, or a real clue as to how to do so. It was made in Hong Kong, but I don't know by what company.

Cut one side of the old and get as close to the original value as possible. Thanks.
