Lindal Pair of 6LQ6 / 6JE6C NOS AmplifierTubes for HF Amplifiers Tested & Guaranteed

 This tube and all others, has been tested on a B&K Dynaquick 700 Tube tester. It shows grid full emission.

TubesThe 6LQ6 is a vintage beam power pentode (also known as a horizontal deflection or "sweep" tube) designed in the late 1960s–1970s for television receivers, particularly color sets. It excels in high-voltage, pulsed applications like horizontal output stages, but ham radio enthusiasts often repurpose it in RF linear amplifiers (e.g., replacing 6KD6 in Hy-Gain models) due to its 30W plate dissipation, low capacitances, and rugged construction. The tube features a 9-pin Novar (Magnoval) base and is electrically identical to equivalents like 6JE6C, 6LF6, 6ME6, and 6MJ6—making it a direct drop-in for many circuits.Lindal Branding Specifics: Lindal Electronics was a major U.S. tube wholesaler and reseller (part of the ITT/Lindal group in the 1960s–1980s) that sourced tubes from manufacturers like Sylvania, GE, RCA, Westinghouse, and Japanese firms (e.g., Hitachi, Toshiba). They repackaged them in distinctive boxes mimicking ITT's design, often labeling them as "Lindal" or "RTT" (Radio TV Tube). Lindal 6LQ6 tubes are typically rebranded OEM units—e.g., a Lindal might have Sylvania internals with green stripes or Westinghouse guts for enhanced cooling (massive radiator fins). They're not a unique "Lindal design" but valued for original packaging and reliability. Production era: Mostly 1970–1980
