Don't see what you need? Contact us. We have many more tubes that are not yet listed.
We also have new and good used tubes in most other numbers including preoctal, globe/balloon,
octal, loctal, miniature, subminature, metal, power, transmitter tubes and many more.
We have metal and glass GT versions of most tubes as well as the 'G' types listed here.
Metal and GT styles are normally at lower prices due to the greater quantities available.
If you need a metal or GT style tube, just send us an email
and we will let you know what we have and the prices.
We have both NOS and used tubes available for most of the tube numbers.
