Subject: Mains Adapters for FX pedals ?
From: GUEST,punkfolkrocker

I'm clearing out junk and wondering if its worth keeping
some mains adapters that were once used to power a set of telephone
battery recharger pods.

These are UK spec: DC 9V 300mA Double insulated.

They are reverse polarity to a standard Boss type FX box power adapter
[eg, Boss PSA-240 adapter 9V 200mA Regulated]
and have smaller connection plugs.

Are there cheap converters plugs easily available to try using them with FX pedals,
or should I not risk it?

I'm guessing that if an adapter is not specificaly marked 'Regulated'
then it most probably isn't, and shouldn't be used with musical equipment ?

I've tried googling but just got confused reading about it..

I've never been any good at electrical theory,
..bunked off a lot of school and dropped out of Physics '0' Level
cuz me and my mates were in a rock band..

So simplified expert advice most welcome please....

I loathe throwing things away,
so if they're not safe to use with FX pedals,
any other suggestions worth keeping them for..

or should I just chuck 'em out and be done with it !!!???

I always keep power supplies. It's easy enough to alter polarity or plug size. I'll even add or subtract rectifiers or regulators if that is what is required in the new application.
The reason is because it is really frustrating to have one fail just when you need the unit that it powers, and there is nowhere within a three-hour journey that can sell you the right sort.
And I'm a natural born miser!
By the way, unregulated power supplies usually connect to devices that have a voltage regulator inside.
Regulated PSU to regulated unit=OK
Unregulated PSU to Unregulated unit=cloud of smoke and visit to the rubbish bin.
