Solid state plug ins are not recommended. The higher voltage will put a strain on the input choke.
Use 3B28 tubes instead.

Other wise you might ruin a transformer someday and you really don't want that. I don't know about the KWS 1, but if the voltage is taken from the centertap, it would not be good.
