Want the smoothest richest tone possible? This kit for the Lone Star Special uses a matched quad of the JJ EL84's for power along with a JJ 5Y3S Rectifier tube. For the front end four standard Gold Pin ECC83S and a balanced Gold pin ECC83S for the phase inverter for a very smooth and rich tone with less grit. 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.
