| 361505 | 2005-06-09 06:24:00 | A well known way to design an electronic oscillator: "design an amplifier". To make an amplifier you have to stop it oscillating. : Those of us who built valve amps years ago invariably made "oscillators" when we first connected the feedback. One learns ... Last year I put together a valve SE amp with no feedback loops, so no problems. A 50 watt oscillator really takes off ...... |

Last year I put together a valve SE amp with no feedback loops, so no problems. A 50 watt oscillator really takes off ...... One of the golden rules I seem to remember with wiring up valve amplifiers, indeed any amplifier, was to use a heavy gauge earth bus-bar that earthed the chassis at only one point near to the input, and to which all other earth connections were made, and also arrange wiring so as to minimise feedback between anode and grid. The old Mullard amps used good wiring practices. |
