KT120 is not always a direct replacement for 6550/KT88 or KT90 (power supply). Please check with your amplifier manufacturer before substituting with KT120.
All our power tubes are computer tested and matched at the highest standards.
They are available as a single tube, matched pairs or matched quads. If you order 8 tubes, we will supply you with 2 matched quads, as close as possible to each other.
We offer a 3 months warranty from shipment date.
We will in no way be held responsible (financially or otherwise) for any damage caused by the misuse of tubes sold by us. It is the sole responsibility of the customer to always refer to the equipment manufacturer with regards to proper tube replacement and, if required, biasing adjustment to be correctly set up by a qualified technician only.
Pricing is for one tube, including Platinium Matching for pairs and quads.
