[AMPS] PL-172 as GG Triode?

[Scott Townley]

I have a homebrewed PL-172 amp deck I'm working on (someone else's I bought
cheap...don't throw rocks at me!).  In tracing thru the circuit, it's a
cathode-driven amp with provision for grid bias, but both the screen and
supressor are DC grounded.  
0V on the supressor causes me no grief (it's even rated there), but 0V on
screen?  I haven't ever seen a Triode-connected PL-172 in the literature
(not that it's not there of course).
Has anyone on the list seen a successful triode-connected PL-172 circuit?
I would think that it would behave similarly to say the 4CX1000A, which
Eimac emphatically states is not suitable for triode-connected service.
Or did this poor fellow frag his expensive bottles?
Thanks in advance!
