BRENT JESSEE RECORDING TUBE SALES
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.
Sencore Model TC-28 Hybrider Tube/Transistor Tester
This is probably the most popular vacuum tube tester Sencore ever made, and one of their best made emissions tester. It is one of the best emissions testers I have ever used, and will make fast, accurate work of your testing needs. It is very easy to learn this tester, and it is FAST! This has sockets for all post WWII tubes, but no 4 or 5 pin antique sockets. Antique tubes with the large pins and no keyway are about the only tubes it WON'T test. It does test compactrons, magnoval, nuvistor, octal, loktal, and all of the miniature glass type tubes, in short, virtually every tube introduced since 1940. It also has a very simple yet complete transistor tester, designed in such a way that it can never become obsolete. Very sensitive shorts/gas/grid leakage tests read directly out on the large meter, catching problem tubes a neon lamp indicator would miss. Life test circuit and a front panel calibration pot round out it's very sophisticated features. Housed in a rugged vinyl over metal brief case, very compact and light weight. All solid state chassis, nothing to wear out. Comes with all manuals, settings booklets and other data. I have one of these testers left in stock, and the tester is 100 percent tested and functional, and is very clean. Our calibration, bench testing, and 30 day guarantee are included in the purchase price. Highlights include:
- Accurate emissions merit test is easily read on the English type GOOD-BAD scale. Microamp scale for balancing tubes on quality of emissions.
- Calibration checked and found to be accurate when compared with more expensive and complex transconductance testers.
- Has sockets for most late model hifi tubes, including nuvistors and compactrons.
- Dual section tubes are quickly checked by resetting just one or more of two switches.
- Individual tube element lock-out switches, which eliminate false shorts test readings.
- Front panel calibration control, to insure accurate tests regardless of line voltage variations.
- Sensitive grid leakage test reads directly on the meter, on a seperate scale. Shows leakage & shorts that a neon indicator will miss.
- Ultra sensitive shorts tests also read directly on the meter.
- Life-test circuit built-in, with front panel activation switch, which will indicate on the meter.
- Simple yet powerful transistor test function tests for gain and leakage of any NPN or PNP transistor. Socket and clip leads built in.
- Audible test tone sounds when transistor gain is satisfactory, plus meter indication. 6-button "softkey" test system cannot become obsolete.
- Original manual and setup booklet included. Simplified instructions mounted in the lid, detailed instructions inside the book.
- Lightweight, and housed in a rugged all-metal carry case with hinged lid, all in excellent condition.
- Our calibration and bench testing of this tester is included in the price.
- $499.00 plus insured shipping.
