Yes. Towards the end of the checkout process there will be a notes section where you will need to request, "middle numbers." This will allow you to put these tubes in your Mesa Boogie.

We can try and match these values to our current stock. Towards the end of the checkout process will be a notes section where you can request specific PC and TC ratings.

We are not able to provide an exact match for tubes without specific matching criteria. If the tubes in the amp have matching information included, it may be possible, but if the tubes were not provided by us originally, it may be difficult even with matching information provided.

The people here always provide exceptional service and there is always someone who can source what I need no matter how old.

The amp I have requires no biasing when switching from EL34's to 6L6gc's. I found that I like the sound of this 6L6 better than the stock JJ or Ruby EL34. The Ruby 6L6 is warmer with less mid bite but combined with a JJ 12axy/Ecc83 it really kicks hard. Awesome.
