QUOTE (scalxwag @ 7 Jan 2005, 12:31)G'day Mike and guys,
I have been under the impression that the SSD stock power supply was unregulated. But I have just found this post at SCI which seems to indicate that it's regulated, and at 13 or so volts. So the advantage of the D3800 is more related to the extra amperage rather than being regulated? Any insights?

I'm still drooling over Drummer's vids - gotta get myself proper power (once I get a functioning power base!).
Cheers.

Sinclair,
it's regulated, clean and variable - and at the moment I find it provides plenty of power for 4 cars. Next step is to try 6 cars, but will be a while before I'm able to attempt that. The extra 1A available over the normal Scalextric supplied power packs seems to make all the difference.

I'd not been aware the standard Scalextric supply was regulated, guess I figured that they weren't normally, so assumed the same here. I did measure voltage from my supplied power pack, and mine gave me 12.28V DC into the power base, which converted to about 13V AC on the track. An aftermarket supply allows you to increase things into the power base above the nominal 12V DC, and for example at about 13.5V DC going in, you get about 15V AC on the track. I wasn't scientific in my measurement recording, hence the use of the phrase 'about', as it was done more from a curiosity standpoint than anything else, as I'd not seen any details about power rates on the forums. And yes, I have taken it above 13.5V DC successfully, without getting an overload - this supply will push out a maximum of 15V DC into the power base, but I didn't measure the resulting AC track level voltage. I'm using a medium priced multimeter.
The single power frustrated me, because of the overloads I experienced with 3/4 drivers, and I chose to buy the D3800 from my supplier rather than experiment with the second Scalextric power pack. I don't get overloads any more, even when reslotting crashed cars. I'm a very happy bunny where Scalextric digital is concerned - just wish my room had more driver access so I could race 6 cars more easily in the future, but alas, room logistics makes 4 my practical limit.
