The ECC34 double triode is a low impedance version of the ECC32. Mullard describe the ECC34 as a low impedance double triode with separate cathodes for use as a combined frame time base oscillator and current amplifier to feed the deflector coils in AC television receivers. It is also suited to instrumentation duties and is pin compatible with the ECC32. The low to medium impedance triodes are the workhorse of instruments such as oscilloscopes etc.
The classic envelope is 43 mm in diameter and, excluding the IO base pins, is 84 mm tall.
