For the most reliable and comparable results, I try to test using both vintage and modern test equipment along with testing in amps when possible. Test results will vary between testers as it is not an exact science and all testers have their limitations.

Will combine shipping. I will send refund promptly once actual shipping cost is determined.

Given the fragile nature of tubes, they will we securely packaged for shipping. Please notify me of any issue or concerns once you receive the items so I can promptly address.

I also have large selection of vintage NOS and vintage used tubes in my store: Tom’s Tone Emporium.

I have been on eBay for over 20 years. Been collecting guitars, vintage amps and tubes for over 30 years as a hobby.
