PS2 3V board, how many LEDs can the headlamp circuit handle?

Lou1985OGR Forum Member

When I've done PS3 steam conversions on my Premier steam locomotives I've run all the LEDs for lighting off the headlamp circuit, up to 8 total, without issue. I use 3mm LEDs with a 470 ohm resistor for the headlight and the other LEDs get 560 ohm resistors. I have a Premier GS4 that I bought a few years ago that was converted from PS1 to PS2 by the previous owner using the PS2 upgrade kit with the PS2 3V board. I'd like to convert it to all LED lighting off the headlamp circuit like on the PS3 steam upgrades I've done. Can the PS2 3V board support 7 or 8 LEDs on the headlamp circuit like the PS32 board used in the PS3 upgrade kits? I just want to make sure before I go ahead with the LED conversion.
