EF80 Telam Tube NEW 6BX6 8D6 Z152 Z719 Pentode Valve Vacuum Tubes, 2pcs

Description: EF80 Telam Tubes, NEW Brand NEW EF80 TELAM (Made in Poland) tubes, equivalent to: 6BX6, 8D6, CV1376, Z152, Z719 I have a total of about 300 tubes, which came directly from several bulk factory boxes. I personally TESTED 5-6 randomly selected tubes. All results were exactly what is expected for NEW EF80 tubes: Anode currents about 10mA, and transconductances about 6.8 mA/V The EF80 internally screened pentode was a workhorse of the TV receiver and was introduced in 1950. It was described by Mullard as: a high slope RF pentode. The EF80 was much used for RF, intermediate frequency, and video amplification. The 'bog standard' TV of the later 1950s was full of EF80s (or equivalents). In those days all British TVs were monochrome, 405-line standard, with a typical video IF of 33 MHz. The EF80 worked well at 40 MHz and also gave adequate performance at up to 100 MHz. The EF80 was superseded in the 1960s by the higher slope EF184. The circuit designer is given maximum flexibility by having all electrodes brought to external pins. Many pentodes have g3, the suppressor grid, internally connected to the cathode.
