* Your AMP12 will need to be sent in to modify (or ask if we have any in stock)

* Please note: depending on stock availability, Audio Note Kaisei may be replaced with the identical sounding Audio Note Seiryu.

Audio Note Seiryu differ only in their leg construction (and of course colour)

Seiryu legs
Tin plating over copper plated steel (Like most other caps)
Attachment is automated on Rubycons machines.

Kaisei legs
Tin Plating over copper.
As copper is softer they are a little thicker and not compatible with Rubycons machines so they require attaching by hand.
This is why stock takes such a long time to replenish (1-2 months)
