Default Cossor 61SPT - any experience?

Hi there,
I have some 61SPT at hand. A quick search however reveals only basic data.
Has anyone experience using this pentode for audio applications? Or maybe some suggestions?

Similar too an 807. Good for RF but not good at LF. In class C they develop a fair bit of power. It can dissipate 65mA or so at 400Volts running at 30MHZ in class C.
