Cobra 2000 GTL RF Final / Driver Transistor Set — 2SD1135, 2SC2166 & 2SC1969 — Working Donor Pull, Made in Taiwan
$179.95
Original Cobra 2000 GTL RF final / driver transistor set removed from a working Made in Taiwan Cobra 2000 GTL donor radio. This donor set includes the visible transistors marked D1135, C2166, and C1969, commonly associated with the Cobra 2000 GTL RF output and driver section.
This set is useful for Cobra 2000 GTL repair, restoration, RF output-stage service, technician bench stock, or parts harvesting. These are original used donor semiconductors and are not modern replacement parts.
The parts were removed from a working donor unit, but buyer should verify transistor markings, gain, leakage, pinout, mounting, insulators, and circuit compatibility before installation. RF output transistors should be installed and biased by an experienced radio technician.
