Summary
| Description |
English: The revised Williamson amplifier, as published in the August 1949 Wireless World article. Power supply components omitted. AC voltages, specified by Williamson in peak volts, shown recalculated to effective sine volts. These correspond to 15W output power (as specified by Williamson). The output stage balancing pot (250 Ohm here) was actually a 150 Ohm fixed + 100 Ohm variable. Otherwise it's all original. The X feedback resistor equals 1200*Sqrt(Zoutput) Ohms. |
