Is an 18.5VDC Power Supply OK to Use with Lionchief?

I'd pick a different one. There are plenty of choices. I searched for "18v 5a power supply" and got many 90 watt variations.

If you use eBay, here's a 90W supply that has a switch selector to choose from a variety of DC output voltages.  Includes a variety of output plugs.  Coincidentally, this picture shows the output set to 18V DC.  

Less than $10 with free-shipping from a US seller.  With eBay, if buying from an Asia seller, be sure to select/specify the USA wall-plug.

Thanks Stan2004. I'm guessing that the one that you have is essentially the same as the two that I linked to and that  the 18V is actually 18–18.5 VDC. But I like under $10, so I picked up the one you suggested.

Consolidated Leo, where were you searching? I tried a handful of platforms, including Ebay, Amazon, Google, Newegg, DigiKey, and Mouser, and found only a few 18V 5A power supplies/AC adapters with a 5.5mm OD/2.5mm ID output plug.

My search was on EBay.

But I thought you didn't care about the connector type as you had one already. Also, the topic from BanjoFlyer indicates that he spliced a new connector to the supply that he got. I guess I misunderstood what you were looking for.

I doubt that a LionChief would not be able to handle the extra half a volt. Since they run on AC or DC, there would be some diodes in there to reduce that voltage by at least that much.

Good luck!

Sorry, I should have been more clear. The connector that I had, I attached to wires with spade terminals, and a circuit breaker in series, which I can attach to one of my spare transformers, a 20W K-Line, and an 80W WBB. But the 18V/5A power supplies are a lot lighter than lugging around the 20 lb. WBB transformer, and for under $20, let alone under $10, why not pick one up.
