Your identifier drawing for the "Sovtek 6L6GC"--I'd suggest adding a remark that this tube is made at Reflector, and it is NOT a true 6L6GC. Its original Russian name was 6P3S, and it is more similar to a 6L6GA than a GC. Maximum plate voltage is 400v and dissipation is only 21 watts (vs. 30 for a true 6L6GC).
