Tubes are available for sale!


Prices have increased due to a 35% tariff, which we hope is temporary. Tubes are not refundable, and if/when prices go back down there will be no refunds of any type.


We are limiting sales to one purchase of up to 8 tubes every 90 days. Sales limits are subject to change.


Please note that if you have a PrimaLuna, you may end up getting twice the power tube life that other brands get.  In fact, if you are running KT120’s or KT150’s they may well last longer than you do!


Please don't try to trick the system or use a friend’s name, etc. Our systems may block your purchase and you can get blacklisted.  Everyone be nice.


At this time, we are unable to send Russian-made tubes to Canada.


Do not ask our sales people about other tubes! This is all that is available right now.
