Can anyone suggest a (very) simple circuit to drive 800Ohm low-wattage speaker (3-5 W max).
I saw in other threads a link to Philips parallel EL86 OTL design, which also looks rather neat - any suggestions for a single tube that would do 2-3 W into 800 Ohm OTL?
Would 12B4A do? Is 6AS7 out of the game because its Rp is too low?
