About Us


We specialize in Analog/Digital Audio Systems, vacuum tube sets and electronic components for many Audio and Radio Frequency (RF) applications including vintage guitar, organ and harp amplifiers, sound effects, mono and stereo HIFI, pro audio, and ham radio.

Our pre-packaged GENERIC, PRIMO and ULTIMO vacuum tube sets use a combination of vintage tubes from the 1940’s to new tubes of the present. All of our tubes are tested, matched when necessary and carefully placed into custom tube sets for our customers at everyday affordable prices.

We often get tubes into our tube lab that are decades old it and it is hard to determine if they are New in the Box (NIB), New Old Stock (NOS), bulk lots sold without boxes, or replacement tubes with great life still left in them. Our extensive experience and comprehensive testing means we throw out a lot of old and new tubes if they test below minimum “NEW” reading on our calibrated tube testers or they don’t pass the LIFE TEST. You can be assured that all the tubes we sell are NIB/NOS or tested new or better according to manufacturer standards. MATCHED TUBE SETS are matched first for manufacturer (tube code, not label) and then for gain/current draw.

We don’t always specify the brands sold in PRIMO Tube sets since we want to give you the BEST VALUE for the price. Some tube sets have brand options such as EHX = Electro Harmonix, JJ, GNLX (Genalex), VA = Valve Art, Russian and the choice is ours unless you specify a brand preference prior to shipment. With over 10,000 satisfied customers our quality control, selection criteria and value pricing have proven results, so we are confident that you will be pleased with your purchase.

For customers who want specific tube brands, these are often available as individual or matching tube sets. Click on the Individual Tubes by Brand or Individual Tube Sets by Type links to the left of this description for a great selection or ask us before you bid.

We arrange all the individual tubes we sell into several classes to make it easier to find what you need. The classes include

TUBEMEISTER is NOT an authorized distributor or dealer for parts or services of the amplifier manufacturer described in this auction and our products have NOT been endorsed or certified by the amplifier manufacturer. While many customers have had excellent results using our tube sets and other products, use of the products sold in this listing may void or modify your amplifier manufacturer’s warranty. We provide sets of tubes from various tube manufacturers (usually other than the amplifier manufacturer) that will work in amps described in this auction. If you need genuine parts from the manufacturer of your amplifier, check for authorized dealers and distributors via the manufacturer’s website.

Use of manufacturer's name, brand name or other registered trademark or sales mark in this auction are for brand recognition and model description purposes only not to be confused with our trade name or logo. WE DO NOT knowingly infringe on others established intellectual property rights. Anyone claiming such violations for questions or comments regarding usage please contact us.

Our Refund and Product Warranty

TUBEMEISTER warrants against “DOA” (“dead-on-arrival”) or differences between an item description (exclusive of illustrative pictures) and the items received. Any DOA or defective item should be returned (e.g. in transit back to us with a copy of the invoice) within 7 days of your receipt of the item and notification to us using Ebay messaging for our record. Please include a brief description of the problem and use your eBay ID in all correspondence.

Due to the many variations in circuit components including the condition and aging of capacitors, resistors, etc, we can not guarantee how a particular tube will sound in your equipment compared to your current tubes. Our tube set configurations are based upon customer feedback of tubes that sound good and are the most popular for the amp/preamp/radio. We offer custom configurations by individual request but we don't accept returns for tubes that are fully functionsal but "don't sound good" or "don't look new" (many vintage NOS tubes lose their label when cleaned and we repackage tubes in new boxes when the old boxes are no longer usable).

Occasionally we ship the wrong tube or tube set and we will gladly replace the wrong shipment with the proper item at our cost. We test all tubes prior to shipment and warrant that they test as “new” or better on our calibrated tube tester. Due to differences in vintage tube gear we can not guarantee that the tubes will test the same in your tube tester or will meet the specifications of your particular equipment or are fit for a particular application.

We DO NOT WARRANT the operation of our tubes in defective amplifiers or electronic equipment! If you plug our tubes into your equipment and the tubes fail to light up or flash on power up or otherwise fail and upon return to our labs we measure dead tubes, then you WILL NOT RECEIVE A REFUND for the tubes returned. Make sure your amplifier/electronic equipment is operational before you plug in new tubes (from us or any other vendor). If you are not sure, take your equipment to a qualified technician who can install our tubes correctly.

If you need to return your purchase and request a refund, we do not refund shipping and insurance charges that were incurred to ship the product to you or return the product to us. If your purchase has a refund option (check the auction), we will issue a refund only after the products are returned and have been verified to be the same ones sent and also test new or better on our tube tester. Purchase refunds will be in the same form as purchase payments.

Email and Feedback Policy

Please use EBAY's mail message forwarding system ONLY as we cannot reply to email sent to our Paypal address. We use the EBAY email system to contact you and it works very well for us. Ask questions before bidding about anything concerning the auction and shipping to your location. Communication between buyer and seller makes for a smooth transaction for both of us!

FEEDBACK POLICY: We want satisfied customers and try to give good feedback to all buyers who pay on time and who have given us positive feedback. Our Feedback to you is usually provided when the transaction has been COMPLETED. (We have received payment, you have received the merchandise, are satisfied with the transaction and have given us feedback.) If you have any problem with merchandise or the transaction or late shipment or are thinking of leaving neutral or negative feedback or anything less than a FIVE STAR rating in all categories, PLEASE CONTACT US using eBay messaging so we can resolve the problem to your satisfaction!

We Buy Back Your Old Tubes!

TUBEMEISTER needs your help to save the planet and we will pay you for your efforts by paying for your old tubes after you buy a new replacement set from us. We cringe just thinking about our great customers throwing away their old tubes which end up in the local dump. Many times the old tubes have hours of good life and great tunes left in them for people to enjoy. We set up a tube recycling program where you get cash for your good tubes returned to us. We test and recycle them to new customers at great prices, and the planet has a few less pieces of glass and metal buried for hundreds of years!

Credits typically run a maximum (all tubes reusable) 20-25% of the original tube set prices so you have a real incentive to buy from us and also recycle your old tubes. Ask other vendors to issue a trade in credit and they only laugh at you! We pay you hard cash for your reusable tubes and that is just another reason to buy from TUBEMEISTER! A Recycle form is sent with your tube set and instructions on returning your old tubes.
