The only audiophile aftermarket 16VAC (not to be confused with 16VDC) power supply I'm aware of is a Swagman Lab product designed as a Schiit PSU upgrade:http://www.swagmanlab.com/Product_PSU?product_id=670
Here's an eBay listing from a US seller:

The unit in the eBay ad looks lovely and I might not be able to build it myself for $80-90 bux, **if** I could find the perfect toroid... so it seems a decent value.
It may be crazy but I can buy the top-o'-the-line doorbell/ annunciator/ thermostat transformerfor $20 bux- the universal voltage for all the world's doorbells being 16 volts, oddly enough. The top of the range is 20 watts on the nameplate. They look like garden-variety E-I type transformers. To save embarrassment I might hide it in an attractive project box behind the rig tho... don't want anybody to mistake my sophisticated HiFi for the furnace! Powered by NuTone, baby!
Isn't the PS you are using now external?? I don't understand the cutting traces thing if you are using a wall wart. There are some PS's under $100 that look good. You could ask if 15v would work and you said the wall wart is putting 18.2v so you have some lee way. T456

The rectifier and filter is inside the little amp, SMD's on the board.
That yugeeeee tranny, a BIG FAT ac wire, a filter cap upgrade on the board if needed and a decent plug and you will have a much improved unit,IMHO. A much bigger sound if that is what you would like. Yuggger is yugely better as I always say. Bigly. And maybe some bigy and better diodes. T456

Here's a better image of the Swagman Lab product. Looks like it features a rather nice toroidal transformer.
