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.

May 19, 2012 11:33Bagaimana cara memecah tabungnya? Apakah seperti memecah telur?
Saya juga ingin membuka tabung-tabung yang sudah KO untuk sekedar ingin tahu dalemannya.
Kita mestinya dapat memproduksi tabung dengan mempelajari tabung yang ada.

Diketok saja Mas, pakai palu atau tang. Tapi dengan kekuatan yang “secukupnya” saja dan jangan langsung melainkan dilapisi kain terlebih dahulu (selain supaya pecahan tidak terpencar, juga untuk memperlemah benturan saat dipecahkan).
Thanks.
