Thanks, I’ll have a go at this. It’s cheap as chips so well worth a go! Thanks again.

I might try the copper tape route for my Classic track. I’d assumed it was only for fixed circuits but it sounds as if you have wrapped it into the connections of individual pieces? Do you have a recommendation as to source/brand/type/size? I have seen 5mm but I’m guessing I need to find 3mm? And I think I need some with conductive adhesive? Thanks again for the help and advice, there’s so much to learn!

Thanks for the extra details, and all the earlier advice. Yeah, not planning to replicate the LeMans 24hr and I tend to keep a shade on my Velux in the loft! It seems even the standard power supply may be enough, and the Pro one is a good alternative if necessary. Just need to make sure I keep that Classic track in good nick, or gradually replace it if necessary, but I have 3 power boost cables already, and could split one to make two Sport to Classic boosts too, so all should be fine!

Thanks for all the advice Andy. Yes, I think this is the route I’m going to take, someone else has pointed me in that direction too. I’ve also discovered that the C912/C990 power supplies with the Sport powerbase only deliver about 800mA each so even the basic Arc Air 1.5A power supply is similar to my two supplies! The Arc Pro power supply (or the Toshiba alternative) should be more than enough if necessary.

Thanks for this. I'd love to go with Air but based on your advice, I may be best sticking with what I have as the circuit is a little over 23 metres in length! I do have power boost cables in a couple of places and my old track has had a good clean but I do notice a drop in performance in parts of the Classic sections, hence my concern about power supply. And I can't go with the copper tape because it's only semi-permanent and may have to be dismantled and stored from time to time. Just to clarify, with Pro and two transformers, would I get the benefit of the extra power in analogue mode, or only in digital? And also, could you please explain what you mean by “Use the Arc Pro powerbase with the Arc Air powerbase?” Sorry about all the questions but I’m still learning all this stuff. It was a lot simpler back in the 70s and early 80s!

I have built a large circuit, with 50/50 Classic and Sport track. I use a standard Sport switchable (one or two transformer) power supply with two transformers. Although it does work using just one, I find the power is smoother using two. But I’m thinking of adding Arc Air to bring it more up to date and have read about issues with the power, especially with older track. Please can anyone comment on whether the Air is sufficiently powerful for a large mixed circuit with just the one transformer as I certainly found adding the second to the standard one helped. Is Arc more powerful than the older one, does anyone have power output figures?Im not currently too interested in digital as I have so many older cars but I understand the Arc Pro can have two transformers, mainly for digitally racing 4-6 cars. In analogue mode, will having two transformers make a difference, can it still feed power separately to each lane?Thank you for any advice you can offer.
