VACUUM TUBE TESTERS FOR SALE



I have some vintage vacuum tube testers for sale, and are listed here on this page. Anyone who has a sizeable investment in vacuum tubes or vacuum tube hi-fi equipment owes it to themselves to have a good tube tester on hand to periodically check the tubes they are using. You can take a more active role in "tube rolling" as you can match your own pairs, and keep tabs on the tubes you are currently using and know well in advance of when replacement time is near.

Tube testers have been out of production since the late 1970s, and supplies are only fair at this time. The prices have been steadily on the rise, especially with the frenzied buying of certain vintage testers on eBay and other online auction sites. Some of these sell prices of certain brands and models are grossly inflated. Hopefully on this webpage I can present good vintage tube testers at reasonable prices, away from the frenzy of the online auctionplace.

NEW! The Alessandro Bias and Matching Meter

This very cool dual test meter lets you regain control over your amp's sonic output. Any time you replace power audio tubes the bias of your amp should be checked and/or adjusted. As power tubes age, the bias should periodically be rechecked and adjusted as needed, or the tubes replaced if they have drifted out of tolerance. This is a brand new currently manufactured unit, not used or refurbished, and we have many of these in stock. This unit is remarkably quick and easy to use. Works with 6L6, 6V6, 6F6, 6K6, 5881, EL34 / 6CA7, 7581, 7591, 7027, 6550, KT66, KT77, KT88 or any octal tube with the plate on pin 3. Can be used with guitar amps or hi-fi amps! You merely install the bias tool twin sockets into each pair of power tube sockets in your amp, and then install the power tubes into the amp through the bias sockets. Turn on the amp, then check and adjust the bias current balance using the accurate twin meters. It is fast, accurate, and easy! Highlights include:

NOTE: This test instrument is only recommended for those who have electrical safety training. There are dangerous voltages inside of any amplifier, and opening an amp exposes the user to these hazardous voltages. The Alessandro Bias Meter is not recommended for those without training in basic electronics, amplifier servicing, or those not qualified or trained to work on electronics.
