| + | If using the amplifier with a function generator, triple check that the function generator output is actually turned on when you're turning up the volume. Apparently, when the function generator is turned on but the output is disabled, the frequency that the generator is set to still comes through but at a much lower amplitude. This has confounded people multiple times, as it's easy to look over. | ||

| Moderate voltages are involved with this. By estimation (60W with 8Ω speakers) it should be outputting only up to 20V... But that hasn't been tested, so take typical precautions and don't touch the leads while the volume is turned up. | Moderate voltages are involved with this.
