NICE CONDITION SENOCRE MODEL TC28 TC-28 "HYBRIDER" TUBE AND TRANSISTOR TESTER
This is probably the most popular vacuum tube tester Sencore ever made, and one of their best. It is one of the best emissions testers and will make fast, accurate work of your testing needs. 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. 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.
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. 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. Tube setup booklet permanently attached, can't get lost. 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 good condition.
