Raspberry Pi 3 Complete Starter Kit - 32 GB Edition This 503HTA Hybrid Tube Amplifier is yet another highly successful Kickstarter project that is built around the Raspberry Pi single board computer (SBC). The project has far exceeded its support goal of $20,000 with $78,744 already pledged and 25 days still to go. Per the website: There is now a $100K "Stretch Goal # 2" to upgrade capacitors, the power switch, and a volume control option.

Vacuum tube products, once the domain of vintage
equipment collectors and restorers (like moi), are
increasingly becoming part of the mainstream retro electronics movement. Usually
the tube portion of a circuit is limited to the output amplifier or maybe a preamplifier
in an audio frequency application, where amplitude stability is not a major performance
factor. RF tuning and detector circuits use, thankfully, modern microelectronic
components in order to benefit from precision digital tuning and even computer interfaces.
Audiophiles have long held that the microphonic action of physical elements within
the vacuum tube adds a warm quality to sound that cannot be replicated with solid
state devices.
