Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

I found some... Could yhis be usefull?

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?
