Recommend a lightweight pedal power supply please!

My son wants to replace the steel box Power Plant unit that currently supplies most of his pedals on his board with something a lot lighter. Recommendations please! Cheers

How many pedals need to be powered and do any of them require anything other than 9v? Also, any pedals that require more than just a few mA? Does it need to have more outputs than that for future expansion?

Can you link to the existing supply, or give us the weight of it?

And is there a max. budget?

No, nothing special, just six regular boss type 9v requirements, he powers a couple of other ones (Digitech X7 or whatever it is) direct. He currently uses one of these: https://www.thomann.de/gb/harley_benton_powerplant.htm It's great but overkill for his current (teehee) needs and weighs a ton.*

Budget, hmmm under £75

*Not the actual weight.

If it's this one, https://www.thomann.de/gb/harley_benton_powerplant.htm then it's 1KG, there is a (albeit more expensive) supply with similar specs but only 200g https://www.thomann.de/gb/harley_benton ... _2_pro.htm @ 58€ or https://www.thomann.de/gb/harley_benton ... _1_pro.htm @ 49€, not used any of them so can't comment on quality.

As I mentioned in the other pedalboard post, those Harley Benton external PSUs will come with adaptors, and with the (bloody awful) style of the PSU used (not great even on Europlugs), it's not going to be stable.

Yes the one he has currently has a proper kettle lead (DON'T CALL IT A KETTLE LEAD! shouts Hugh from the wings).

But this might be a good alternative, no wall wart etc https://www.thomann.de/gb/harley_benton_powerplant_junior.htm

It is 920g though, only 80g less than his current one going by the manual specs.

This might do it though, https://www.thomann.de/gb/trex_fuel_tank_junior.htm
5 outputs, figure 8 input

Has he weighed his pedalboard? Boss pedals weigh around 400g, a Pedaltrain Junior weighs 1.4kG so 6 boss pedals and board plus that PSU weighs around 5.8kg (and you say he has at least one other pedal with a separate PSU on there?)*. so he's saving slightly more than the weight of one Boss pedal or about 8%. Seems a little pointless to me TBH as even carrying it on the bus with a guitar in a gig bag he probably won't feel any difference. If he's just loading into and out of a car..............

* The lighter ones suggested only have 5 outputs BTW

He’s just got a new smaller lighter board plus some mini pedals eg a Tc polytune mini to replace his Boss tuner so as Tesco says every little helps.

Fair enough, I have a couple of smaller boards as well as the big one and mix and match pedals on them according to the gig.

They may work fine, or you may get ground-loop noise. The more pedals you have, the more chance of any ground-loop issues. And digital ones are far more likely to suffer than analogue pedals (though some analogue circuits with clock circuits in can also be noisy).

I'm afraid it is all a question of 'maybe'. 50 shades of maybe.

Exactly, the one I bought from a retailer on ebay was very noisy, it was supposed to be a conventional transformer based supply but was actually switch mode and introduced digital hash into the audio path. They were miffed when I sent it back as they could not hear the problem. Maybe they only tested it with a single or a couple of pedals? Either way they would not accept that it was not fit for purpose. OTOH I daisy chain three of four pedals off my Boss PSUs they are fine so just buy a decent iron based PSU with plenty of capacity and buy a cheap daisy chain lead.

The only issue I know for products like this is that they are not isolated, plus if I was getting a PSU I'd either want a branded one or an own brand of a decent dealer. So one like this, https://www.ebay.co.uk/itm/Behringer-Be ... Sw9YNZqDj5 , would probably be better, made for Behringer so will be of guaranteed quality (to an extent) and safety.

Also one thing though that ran alarm bells for the one in the attached listing is that the label is not fitted properly in their picture of a UK one, that I think speaks volumes about the quality of said supply as f they can't even get their stock picture right think about what they may let slide on the ones they are shipping.

I think he means one with a transformer rather than a switching supply, however, if the switching supply is well made and designed for AV equipment not IT equipment then it should be fine.

As stated on t'other thread, I've been using one of these: https://www.gear4music.com/Guitar-and-B ... music/1P94 for one of my pedal boards for quite a few years now with no problems. But it doesn't run anything heavy load - a couple of switching pedals, a chorus, a delay and a tremolo (all analogue).
YMMV

I really wouldn't skimp on the PSU - those mass market rebrands are rarely isolated and free of noise even if they claim to be...

I have a T Rex fuel tank isolated that works well...
The 1 Spot stuff is also good....
