While I was mistaken the last time by my own all too quick measurement, an opportunity for a really cheap 24 V (DC) power supply with linear regulation for amps like the PortaCorda series just had to turn up sooner or later. Well, there it is: Thingy is called APS524, does 230 V (AC) to 12/15/18/20/22/24V and 550 mA - and you can order it for the enormous price of 3.95 Euro over there: http://www.pollin.de/shop/shop.php?c...=ODk1OTc5&ts=0
I've already received a couple of these today - first impression is quite positive, cause it's not too cheaply built. You can even open it up (provided that you have the appropriate security bit a hand) - inside you'll find the usual components, including a more-or-less no name 1000 µF buffer cap and an NS LM317T linear regulator, which is attached to a trustworthily big passive cooler. And there even is a bit of thermal grease to be seen - all for 3.95: I mean like... WOW!
Only problem for the electronics impaired might be that the voltage selector has no markings - so one should better have a voltmeter at hand for the initial set-up. In addition, one might doubt the 550 mA given the size of the transformator - I'd assume it to do 550 mA for 12 V only, and half of that at 24 V (= still plenty enough for most portable headphone amps).
Alas, no further testing on my side yet - 'cause first I now have to go digging for that *$&!*%§ angled plud Jan Meier usually provides with the PortaCorda II...

P.P.S.: Standard comforter: Yes, I already did business with 'em twice as a customer - and so far it was free of hassle.
P.P.P.S.: Just btw, they also still have those cheap conventional 115 V<->230 V converters - 100 W for 15.95 Euro (http://www.pollin.de/shop/shop.php?c...=Njk1OTc5&ts=0 - mind you the photo is not correct, though: As stated in the German description, there's only one US outlet on the 100 W unit...), and 500 W for 29.95 (http://www.pollin.de/shop/shop.php?c...=Njk1OTc5&ts=0)
