can el85 be used in a lite iib ? Any changes required ?

is it safe to assume that the values used in ecl86 output stages will be suitable for el85 also ? There doesn't seem to be many el85 amps documented on the web!

Both specs here.

The following link is a useful resource but sadly doesn't have the EL95 but it has the ECL86 and typical operating conditions for EL85 are on the EL85 pdf above

Hope this helps

Thanks for that David; does anyone have any ballpark suggestions about cathode biasing resistor value? The mullard data refers to 310r in the operating conditions section fpr AB push pull~ so does that suggest a shared resistor of 150r to 180r for starters?
