Hi @dolanchomsky
Might be better to go with a 24V 7A AC/DC adapter (or even one with a slightly higher current output e.g. 8-10A if you have one) which has the correct size barrel plug connector.
The amp will only draw as much current as it needs to, at any one time. As long as the voltage supply is exactly the same, i.e. 24V DC, it will be fine.
The only way it will draw more current that could cause some damage, is if the voltage is increased beyond 24V or there's a fault in the amp.
Hi @dolanchomsky
It's not a case of a "smaller straw" as the maximum value of current required to power all the functions of the amp is a known amount due to the circuit design. So the amp will never draw more than this from the power source. It may even draw less depending on what components in the amp e.g. BT etc are being used or not used at the time
Most DC coax (barrel type) power plugs are usually in the following sizes and usually come with current ratings as well
- Type A: 5.5 mm OD, 2.1 mm ID (with optional screw lock)
- Type A: 5.5 mm OD, 2.5 mm ID (with optional screw lock)
- Type B: 6.0 mm OD, 2.1 mm ID
- Type B: 6.0 mm OD, 2.5 mm ID
- Type C: 3.8 mm OD, 1.1 mm ID
- Type D: 6.3 mm OD, 3.1 mm ID
- Type E: 3.4 mm OD, 1.3 mm ID
The hard part is if they're a type A or a type B and you have to choose which one to fit the socket that you want to connect to
A type A or B 2.5mm ID plug will fit into a corresponding OD size Type A or B 2.1mm ID socket but it will be an intermittent connection i.e. sometimes there, sometimes not.
A Type A or B 2.1mm ID plug will not fit into a corresponding OD size Type A or B 2.5mm ID socket.
So if you're experiencing intermittent power loss it may be because you have the wrong plug for the socket
