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 and 18 KT120 or KT150 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.


Let us know if you have a large project, we can help you out.


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.

Tung-Sol 5881 

New production tube made by New Sensor in the Reflektor factory in Russia. Gotta 5881 amp and you're sick of using the same old Sovteks? Folks are really getting into this current production homage to the legendary Tung-Sol. Similar in looks to the original U.S. version, and folks "in the know" say they sound similar too.

The 5881 can be used as a replacement for the 6L6GC, however it is a lower dissipation tube, which means less power, and you may need to back off the bias slightly depending on your amplifier. Consult your amp's owner's manual first. To be honest... if your amp can use the 6L6GC, I'd stick with that.

Pricing above includes matching in any quantity you need at no extra charge.

All power tubes are Platinum Screened & Tested to the highest standards, including a 72-hour burn in process, and testing at real-world voltages.
