Use a current-limited bench power supply or place a low-wattage resistor in series with the power line for the first power-up. If the resistor gets hot, turn off the power immediately.

How to Find and Use "Practical Audio Amplifier Circuit Projects PDF" To find effective projects, focus on reputable sources:

A variable resistor paired with a transistor mounted directly to the main heatsink prevents thermal runaway. As the temperature rises, the bias voltage drops safely.

Guitar Tube Preamp with Solid‑State Power Stage: For tone experimentation, combine a small vacuum tube preamp with a solid‑state power amplifier. Objectives: explore nonlinear coloration, impedance matching, and safety when handling high voltages.
