Understatement!!
I've never found two the same! Yours has a 6V6, both of mine have a 6BW6 (which is basically the B9A equivalent). One of mine has 3x 8.2K resistors in the HT rail, the other has a large 15K. Another variation is a tapped output transformer for hum-bucking. One of mine has it, the other doesn't. Oh yes and one has a ferrite rod and the other doesn't.....
There's loads more variations as well.....
Don't know about the .001. According to the Trader sheet 969, S2 connects to the LW trimmer which is only 70pF. A .001 here will just about kill any signal. The only .001 listed is the aerial coupling capacitor.
None of the versions have a 25uF capacitor on the output valve cathode so you can do away with that.
