Want a very smooth and rich tone with less grit for your Bravo? This is our Gold Pin Retube Kit. It contains a matched pair of JJ EL84's for power along with two standard Gold Pin ECC83S's for V1-V2 and a graded high current Gold Pin ECC83S for V3. Just let us know in the comments section if you're looking for max headroom, moderate or an early breakup so we can select a proper grade for the power tubes.
