I found some cute suggarcube-sized SMPS in the socket of GU10 (5W) LED light bulbs.
Having those loaded with 23 Ohm gave me an output of 5Vdc and 200mA (=1W)
I figure this could be used as a filament supply for my Telefunken RE114 DHT´s (calling for 4V / 150mA filaments)which has previousy been feed with a battery supply.
Since the RE114 is from the 20-30-ties I am a bit worried though about if inrush current etc could burn the cold delicate filaments of the RE114.
Any thoughts?
