Description
The Philips EFL200 (6Y9) is a twin pentode in a 10-pin Loctal-style envelope, manufactured as NOS by Philips in Australia. Its twin-pentode configuration allowed compact single-valve audio output stages in European-designed radios.
These are primarily of interest to restorers of period European equipment built or sold in Australia. Stock is limited and these are infrequently seen in good NOS condition.
10L pinout. NOS, made in Australia by Philips. A single valve is supplied.
