Vacuum Tubes

  • 1 kHz, 15% THD waveform, 8.7 W

    SE 6L6 Amp

    I wanted to create a reasonably loud and simple amp without extra crap like tone control. Just a plug and play amp that sounded good with maximum one knob. I also wanted to use a 6L6 and some older types of tubes (octals), just for show.

    Magic Eye Tubes

    Magic Eye tubes were the first electronic indicators (not counting the electromagnetic meters). In consumer radios they were used as tuning indicators (pre-50's). For a long time, they were the only available visual indicators with no moving parts. They are also the precursor to cathode ray tubes (otherwise known as TVs).
