Oldamp MAKE amends for 02! Page 116, 3b should read: “Reconnect the capacitor, switch the meter to DC voltage, turn off the input signal, and measure across the capacitor. Ours read 74 volts (V). The voltage rating on the capacitor is 75 volts, so there is not much margin in this old amp.” The title for the “Testing current/amperage” figure should be “Testing BFC current”. The title for “Testing Voltage” should be “Testing Output Current”. Link.
