After previous trip to “trash bin” shop, now it’s the time to test it ;) So I open my old Knight 600 Tube Tester and fire it up.

Picture below shows my Knight 600 testing Amperex 6BQ5/EL84 tube. Not bad! No short or what-so-ever.

Below picture shows my old Knight 600 Tube Tester. I need to calibrate and do some restoration project, later… Time is an expensive things right now. I don’t have many :(

It was made for US electricity, so we are playing with 110V. I need to power up my step down transformer  (we use 220V here).

The Knight 600 is testing my Amperex 6BQ5/EL84 tube. Well, not a bad result. The Gas Test (not shown) also produces good reading. The bright yellow square is the roll-chart, backlighted with neon to give vintage sensation (they did the very good job).

The roll chart of Knight 600, lighted with neon backlight. Produces a “old/vintage” sensation.

My GE 12AU7. I just love to take photo of various tubes, to see how does it light.

My favorite shoot, 0A2 (similar with 0D3). This 150V (VR150) voltage regulator produce “cute” purple color.

    halo koko Jimmy,salam kenal yah, saya baru main-main dengan tabung nih,jadi saya mau tanya itu koq foto diatas yg 12AU7 koq sepertinya terang banget yah, koq preamp yg saya rakit pake 12ax7 dan 12au7 sepertinya gak seterang itu,malah susah terlihat nyalanya(redup), tegangan filament nya saya pake 12,6 V, apa memang nyalanya seterang itu? tlg kasi tau yah koko Jimmy

    Hi,
    Mungkin pada kenyataannya tidak seterang yang di foto, karena di foto menggunakan long shutter time dan kondisi ruangan gelap, sehingga efeknya lampu terasa lebih terang.

    Thanks.
