The difference between EABC80 / 6AK8 and 6T8: The EABC80 / 6AK8 has a better shielding between heater and the other electrodes, particularly to the triode control grid, in order to suppress hum. Otherwise they are interchangeable to each other.

The EABC80 was specifically designed (1954) for use in the detector stage of early FM and FM/AM radios. The triode section providing the first audio amplification, the single diode and one of the diode pair were used as an FM detector in a ratio detector circuit.

Aug 12, 2013 · EABC80 was used in typical European tube radios. It formed AM detector, FM ratio detector and AF-preamplifier. The EBC90/6AT6 is half a 5751, plus two diodes. It is sometimes used in circuits where just one good audio triode is needed. EBC91/6AV6 is similar, but half an ECC83/12AX7 instead.

These EABC80 tubes were primarily created for use in early AM/FM and FM radios as part of the detector stage, allowing the audio signal to be transmitted through the receiver. In fact, although they are nominally different, the EABC80 tube is often used as a replacement for the 6T8.

Original Stock Made In Germany in the 1950's. The Telefunken EABC80 vacuum tube is a miniature type used as a combined audio amplifier, AM detector and FM detector in AM/FM radio receivers. They require a miniature 9-contact socket. Reverb has your back if your item is lost, damaged, or doesn't match its description.

The Mullard EABC80 is a quality tube perfect for your application. Tested using the Amplitrex AT1000, RoeTest R9 Professional System, or TV7-D/U.
