Cla58 Driver Top -
If you are deploying this across multiple machines, consider packaging the driver into a silent install script using tools like pnputil to save time.

Due to the demand, several sources offer CLA58 driver tops. Beware of eBay listings from unknown sellers. Recommended sources: cla58 driver top
Price range: $25–$80 USD depending on component quality and whether driver/output transistors are included.
Use high-temperature, stranded wire (18–22 AWG). Wire in this order:
| CLA58 Terminal | Connect To | | :--- | :--- | | V+ | Main filter capacitor positive (via fuse) | | V- | Main filter capacitor negative (via fuse) | | GND | Power supply ground (star ground point) | | INPUT+ | Preamplifier output / RCA center pin | | INPUT- | Signal ground | | OUTPUT (Base drive) | To the bases of the main output transistors (through 10-ohm base stopper resistors if not onboard) | | BIAS SENSE | Thermal compensation transistor (mount on heat sink) | If you are deploying this across multiple machines,
When selecting or designing a driver stage for ~58V rails, prioritize:
| Parameter | Typical Value for 58V Rail | Why It Matters | |-----------|----------------------------|----------------| | Gate Drive Voltage | 10V–12V (VGS) | Ensures MOSFET fully turns on (RDS(on) minimum). | | Peak Sink/Source Current | 1A – 4A | Determines how fast MOSFET gates charge/discharge. Faster = lower switching loss. | | Dead Time | 20ns – 50ns | Prevents shoot-through; must be adjustable or adaptive. | | UVLO (Under-Voltage Lockout) | >6V on gate supply | Prevents MOSFETs from operating in linear region. | | Max Supply (PVDD) | 65V – 70V absolute max | Must have margin above 58V (e.g., use 80V-rated MOSFETs). |
