Please note that due the huge variation in tube amp designs, we as a tube vendor cannot guarantee our tubes are 100% compatible to your amplifier. Each tube model description on this website includes a spec sheet link – please feel free to forward it to your amp manufacturer to confirm compatibility before you make purchase.

We cannot make recommendations on tube substitution on a particular amplifier model due to liability reasons. Your amp manufacturer or distributor is your best source of information on such a topic.

Please also check the physical measurement of the tube you are about to purchase, especially if your amp has limited space for installing tubes. Some amps have recessed chassis which could limit space available to install different tubes.

Returns due to compatibility issue listed above will be subject to 20% re-stocking fee at all circumstances.

Thank you for your understanding.
