Steve K helped me with this on my last one but I forgot what the ratings/bias should be??
Any help???
It has KT 88 in it right now
 
Not sure of the plate voltage in the Shiva but They are usually between 48/51 mA
 
PV is high so Winged C is best. I redplated two pairs of NOS 6550 in my Shiva. Bias at 43ma if your PV is 500-505
