Tube Substitutes for the SE84

Currently investigating the Decware SE84 kit. The tubes used are some fairly commonly available tubes with a number of interesting equivalents. I like the tube complement because you can get a huge range of NOS, current production and Russian/Chinese equivalents. Great opportunity for tube rolling!

Input: 6DJ8, 6922, 6N1P, E88CC, E88CC/01, ECC88, CV2493,CV2492, E188CC, 7308, E288CC, CCa, 6N23P or 6H23, 6N11, 7DJ8 (different 7V heater).

Refer to this link for more info.

Output: EL84, 6BQ5, SV83, 7189, 7189A, CV10321, CV2975, CV8069, N709, 6P15, 6P14P.
