Since I never got around to building Eiclones, I tried a different approach and built P to P drivers for my MK-3s using the Ike circuit and octal tubes.
The tubes are 6SF5 for the VA and 6SN7 PI. It sounds excellent with EL34's but when I can afford (and find) another pair of Sylvania 6550 tubes to go along with the pair I have, the EL34's wil have to do.
