If you’re interested in purchasing a fully assembled and tested amplifier, a complete amplifier kit, or just the chassis, feel free to reach out to me at ricardo@heatedcathode.com. I will respond promptly with details on pricing, payment options, and shipping.
Estimated Pricing
Due to fluctuating electronic component costs, I cannot provide fixed prices. I am committed to using only the highest-quality components, carefully selected to ensure long-lasting performance and electrical safety.
Each amplifier is handcrafted as a hobby, and components are sourced in small quantities. I typically do not keep regular stock and build each unit on demand. Therefore, if you’re interested in placing an order, please contact me via email to confirm current pricing.
Below are approximate prices for reference:

Safety Notice

The high voltages present in this circuit can cause electric shock, which may be potentially lethal. As such, I cannot be held responsible for any accidents, injuries, or damages resulting from the use of this circuit.
If you purchase the kit parts to assemble the device, advanced knowledge of electronic components, circuit assembly, and soldering is highly recommended, as this is not a beginner-friendly project.
