High quality, sturdy construction. Modeled after the Phillips STR power tube of the 50s and 60s. Full rich tone, very musical.

    The new tubes sound amazing and really brought my amp to life. I will definitely be buying tubes here again in the future. Very happy with my purchase and quality of the tubes.

    Really like the 9th gen Chinese made tubes. They seem to have a “vintage” quality to them. Unfortunately, I’ve been hearing of the plant shutting down or moving. I’d be very sad if these were no longer available. An excellent choice for a current production 6L6.

    Tubes arrived in good condition and seem to balance easily.
