Flat Dog power supply

raithza

I'm currently looking for an affordable power supply for my pedals (currently just an digitech stompbox, dunlop crybaby and zoom 505) and came across the Flat Dog ad on gumtree ( http://capetown.gumtree.co.za/c-Stuff-for-Sale-musical-instruments-Power-Supply-W0QQAdIdZ206036925# ) but I can't really come across any info for them. Anyone have any experience? and why would a Daisy chain be supplied with the PSU, if it has several power outs?

It looks locally made, for better or worse, my guess is that it just has a single, non isolated regulator, making it no difference from some of the other options, and not much cheaper. RE the issue of a daisy chain, it is prob cheaper than making up single cables, since you need a connector on each end, so it is done to save costs.

Some more info from the maker:

SPECIFICATION:
1. Power supply in AC 220v 50 htz.
2. Power supply out 9v DC 500 mA
3. Daisy Chain supplied centre pin (-) output.
4. Fuse Protected.
ASSESSORIES:
1. 1 x 220v Mains chord.
2. 1 x Daisy Chain with 4 outputs centre pin (-).
3. 1 x ¼” to 3,2mm adaptor plug.
4. Spare 15 Amp Fuse.
GENERAL:
1. This unit will power up to 7 pedals with no feed back or interference if used correctly.
2. Be sure that total pedal demand does not exceed 450 mA .
3. Check pedal polarity before switching on.
4. Make sure unit is switched OFF and unplugged from mains before changing fuse.
5. Keep plastic cover over output when not in use.

They are hand-built locally.

Yes, it is exactly as I thought it would be... though those specs on the fuse are bogus, 15amps? It is a 450mA supply, you want your fuse to blow at rated current or close to, otherwise you have a good chance of burning out the transformer to blowing the regulator... not a BAD price, just not that good either.

+1 on the fuse thing - it should be a 500ma. I also don't like the cheap ripcord wire used for cables. It looks like 1/4" jacks (on a pedalboard that uses the same for audio signals, that is a very bad idea, IMO). Anyway, if outputs aren't isolated, it doesn't give you anything more than a wallwart with a daisy chain does.

What could be even more frightening is that the 15A fuse is the on the transformer primary, selected because mains sockets are rated at 15 amps! A 3.2mm plug? Most pedals use 2.1mm. Don't like the 1/4" jacks either. Imagine your pickups when you plug your guitar cable in by mistake!
