Meanwell 24V 5A power supply and power cord
This is Nelson Pass's recommended power supply for the Amp Camp Amp. Now available for immediate sale.
It gives you more power and less noise than previous power supplies. It's a serious unit - twice the size and twice as heavy as the previous one.
It's a universal PSU and accepts 86-264VAC and 47-63HZ. It has a standard generic IEC power inlet. We are selling this power supply bundled with a high quality 6 foot (1.8M) Linvox 3271V86 IEC power cord with US style plug. If you live internationally, you'll need to borrow an IEC cord ("kettle cord") from your least favorite piece of equipment or use a plug adapter.
Why this power supply?
Nelson Pass tested several candidates for our "new and improved" Amp Camp Amp power source, and this Meanwell GST120A24-P1M power supply had the best performance of all the candidates. Compared to the old power supply, this one:
- More power - about 7wpc
- Improves signal to noise ratio
- Runs cooler
- Comes with a 3 year warranty from a brand well known to be one of the most reliable in the industry
Who is it for?
It is a suitable upgrade for all previous, current and future planned generations of ACA (see note below), and will plug straight in to all previous Amp Camp Amp DC jacks.
It will also drive several other as-yet-undeveloped amps we have on the drawing board for the future. You can consider it an investment in a quality 24VDC power building block that will not be made obsolete for a long time.
About the manufacturer
You've probably already heard of Meanwell. Unlike most PSU manufacturers, 99% of Meanwell's business comes from sales of power supplies bearing the Meanwell name. Over 40 years they've grown to be the 5th largest PSU manufacturer in the world, and the only one in the top 5 who sells supplies using their own brand name.
The result is a brand that has become synonymous with quality and you can be assured that purchasing this PSU is a long term investment in quality power for your projects, and testament to that is the fact that they back this PSU with a 3 year manufacturer warranty.

Notes for upgrading to 24V from 19V previous generations of ACA
"You can use also this supply on the original ACA, but you will want to adjust the DC value on the output up to 12V. You can also adjust the feedback resistor and bias resistors down to the values of the ACA 1.5."
To use the 24V PSU and also bring your ACA up to new 1.6 specification:
- If you have a PCB that says revision 1.0, add bias resistor R15 (increases power to 6W)
- If you have 1.0 or 1.0b, adjust R12 from 68k to 39.2k
- If you have 1.0, 1.0b or 1.1, adjust the DC value on the output to 12V
Better the cheap psu I was using
Good clean power for the ACA. Great service from DIYAudioStore too.
Works Fine, good replacement.
What can be said. Works well. Looks like a brick.
This 24v power supply made an amp that I already loved sound even better and gave it even more power. It now plays as loud as I could want from an amp especially when paired with my subwoofer through the speaker level inputs. I have totally fallen in love with this amp and can say it is the best listening experience I have ever had. And this is just after I paid well over $1000 for a REGA Elex-R amplifier. This amp kit outperforms my Rega amp with clarity very noticeably. I wish I could return the Rega honestly. I biased the DC output to 11.9 volts on both channels after trying it at ~ 12.2 volts. I found it sounded better with the lower number and I am loving this thing now.
