I have built a classic LM317/337 power supply - and it works, giving proper voltage, etc. however when I start it under load (approx. 300mA per regulator) using a switch, the LM337 goes into some sort of protection (audible buzz), but when I start the circuit under load...

Using an incandescent lamp as the "resistor" for a zener/avalanche diode regulated supply

The recent post on using a lamp in series to limit potential fault currents has had me thinking about using them as above. Has anyone done this? I can see advantages, cost for one - wirewound resistors can be expensive. Visual indication of a varying load. Make it "short-circuit proof"..
