This kit contains a matched pair of JJ EL84's for the power section. A JJ ECC803S for V1 which is the clean channel for a little lower gain with big thick mids and a little more sparkle in the highs. Two standard ECC83S's for V2 and V3 and a balanced ECC83S for the phase inverter in V4.
Just let us know in the comments section if you're looking for an early breakup, a moderate breakup or a later breakup for more headroom in which case we will choose the coolest grades we have available for the power tubes.
