well my order of 6j32p never turned up from old ruskie so in the end i've thrown
together 6n2p-->volume-->6n2p-->tone/master-->6p18p
preamp are standard operating at around 220v each. the power amp is a 5k load, 250v plate, 240v screen with 2k2 stopper, 200ohm cathode resistor bypassed with 100uF.

very happy with the sound, so thank you for the pointer people. one of the best amps i've owned to date, i'm currently feeding it into an 8 ohm peavey pacer speaker atm. sounds awesome!!!

two last q's tho, i want to see what it sounds like in triode mode and screen bypassed with cap
the triode mode question is more a case of can i just throw in a mini toggle spdt to change mode when turned off, or would i need a better quality switch?
as for screen bypass i don't quite understaand how to dra the tangent on the tride curve to determine the internal resistances.

seeing as using the anode load yields a lower roll of does that mean i could get away with
c1(in uF)=(1/(2*Pi*40*5000))*10^6=0.79577 so 1uf np? would this be safe? i won't be causing oscillations by doing this will i? also i was going to bypass it to ht rather than cathode, am i right in assuming it makes no difference?
