| iMo:
Any idea what is the filament current of the original display? Thanks. |
| coromonadalix:
10 ohms of impedance / resistance |
| iMo:
Ok, 10ohm, and the voltage is 6V (when looking into the SM p.9-7) therefore 600mA AC, imho. |
| coromonadalix:
6v in 10 ohms is 600ma not 60 ma |
| iMo:
That is a long back I saw something like 600mA :) A pretty large current, my display is normally off (I use BT), so I think I will switch the filament off as well.. Another project.. |
