I know this ube is of limited use to begin with, being a triode-pentode with common cathode, but the documentation i have remains unclear wether the pentode section is remote or sharp cut-off. Can anyone help?
Sharp cutoff. See also 6GJ7, 8GJ7. And of course Fred's paraphase circuit... http://www.dogstar.dantimax.dk/tubestuf/paraph.htm
Taking a look at Frank's website, http://www.mif.pg.gda.pl/homepages/frank/sheets/010/p/PCF801.pdf
the pentode curves look to be somewhat remote cutoff. Also at frank's, http://www.mif.pg.gda.pl/homepages/frank/sheets/124/p/PCF801.pdf it says that it's a remote cutoff pentode.
Unless you want to use it for guitar work, it's probably not usable for audio.
