I break one of my tube (in purpose) to take this shoot. It’s an EF184 made by Philips. I don’t have any use for this tube anyway. So just enjoy the weekend shoot meanwhile I’m soldering my DAC 😉
EF184 is a high gain pentode with frame grid. Mostly was used as IF Amplifier with high operation bandwidth up to 40 MHz in old television receiver.
Imagine how this tube was constructed. Definitely not an easy job and need a steady hand.
The frame grid covering the construction inside.
The bottom side is crowded with a complicated wiring ended into the B7A pins. What a beautiful state of the art construction! I think this is one of the reason of tube-lover loves their tube. Instead of good sound produced, they can also enjoy the build quality and construction of the tube.
