If the only difference is the size/shape of the connector, then probably.

Yeah because the amplifier needs 6.5V and 1.5A, and the adapter is the same. It's just the silly jack which is different. Why they even have two different kinds, I don't know. You can't see which kind it is when you order it on Amazon...

Sometimes they're listed either with their [URL="https://en.wikipedia.org/wiki/Coaxial_power_connector#Adaptaplug"]Inner/Outer diameters and/or their Adaptaplug Name[/URL] (i.e. A, B, C, ...) which corresponds to a particular ID/OD and that respective IEC/EIA standard.
But yeah, that's an inconsequential amount of current, you could just simply solder swap on the new connector.

The manual itself does say ONLY USE A BLACKSTAR APPROVED POWER SUPPLY (PSU-1), and that power supply is really big compared to the one I bought, even though the voltage and current is the same... what can go wrong?

If the voltage and current ratings are the same there isn't anything to go wrong, unless you manage to reverse the polarity.

I can now imagine they are the type of people who would use center-negative connectors.
[QUOTE=Cakebatyr;49800134]I can now imagine they are the type of people who would use center-negative connectors.[/QUOTE]
The people who do that are the markerters/managers who learned a tiny fraction of EE and figured out how to force uninformed people to use their product.
Center negative connectors are the devil's work.
I saw one of you guys a few months back. Connecting a RaspPi to a Camcorder CRT viewfinder.
I'm going to do this for an University project. Do you guys know if all older Camcorder have a miniature CRT? Or should I be looking for something specific?

But why would you make a power supply unit which is like 5 times as heavy as the one I bought? Does it 'last longer' or something? Unfortunately I can't figure out which exact jack is on the amplifier, so I can't buy the correct connector. Most electronic shops are far, far away or just webshops in Helsinki, so I can't really go test out which connector fits.
Guess I'll just have to buy the 'official' PSU :(

Most camcorders before early 2000s would be using a CRT viewfinder.

It may use a different topology that requires bigger components. For example a transformer followed by a linear regulator will be many times bigger than an equivalently powerful DC-DC PSU. And even though it will also be less efficient and thus generate a lot more heat which has to be transported away, it can still be a better choice over a DC-DC-regulator, as the output of a linear supply is less noisy.
On a consumer electronic device it doesn't matter 99.999% of the times though, as long the supply can deliver enough current at the correct voltage.

Is centre-positive the convention?
I always assumed there was no convention because about 50% of the stuff I buy is centre-negative, so I always check :v:

I don't think there's a set standard, its just the de facto for barrel connectors to be center-positive that anybody who designs with center-negative just becomes "That Guy".
Clearly, I define all electrical/electronics standards. :v:

This is just like SMA and RP-SMA. I could vomit every single time.

I just operate under the assumption that putting the live end of the power wire on the outside part of the barrel is generally a bad idea.

I have adapters for every RF connector at this point. Including female N type to male 7/16 DIN.
Wikipedia provides this handy size reference :v:

N-connector best connector though.
It's too bad the radio world pretty much standardized PL259.

We don't use crazy hermaphrodite connectors. Only god fearing Male and Female connectors! Unless they're for power, then we love polarized non-gendered connectors.

Open wire binding posts are the best connectors.

Good luck with those high-frequency signals.
[QUOTE=papkee;49814327]Good luck with those high-frequency signals.[/QUOTE]
I think you'll find that BNC works absolutely fine for High Frequency signals. Its the Super High Frequency and Tremendously High Frequency signals where BNC struggles :v:
Bought some dual-ganged potentiometers
How the fuck do I plug these into a breadboard

Pry on them carefully? Or get some male to female jumper wires on the, or just wire some wires to it worst case...
Dupont male-to-female wires.
Ebay is your friend.

According to wikipedia BNC works up to 4GHz-ish

PCB time.
This isn't the entire thing of course, this bit is just the GM tube and the anode and cathode resistors.
I'm going to put this inside a copper pipe with a window cut in it, power and signal is going to be a BNC bias tee which should be interesting at 400V.

Most of the wireless ISP stuff I deal with is all N. If a tower rigger can use them without problems at the top of a 300 foot tower in february, they must be designed somewhat well.
Ham radio standardized around PL259 because we're dumb and they're stupidly easy to put on coax.
