Topping PA5 Review (Amplifier)

[Vini darko]

I have already closed the chassis and wired.
You can guess the distance from the first photo.

Thanks for the pics. It's a fun thing to chew on

Let the reverse engineering begin!

 

[Vini darko]

Four output inductors show that it is a bridged amp. Usful when dealing with low voltage rails. Pot looks like it might be dual gang too.

While pondering about the layout, $349 aked for that level of build quality alone (not taking into account R&D) does not seem justified at least. It's like a throwback to their early TDA7298, TPA3116 amps from maybe 2014. No comparison to clean contemporary builds by Gustard e/g.

What is troubling you then?

 

[Vini darko]

Might be wrong here.

No need to worry.
It touchs the chassis when it is closed.

The backpanel is loose, just hanging in the wires. When put back together it will most likely touch, you can see from the small shiny mark that it was in contact previously.

That makes sense thanks.

I would like to know as well. The forum is not independent enough?

 

[pickyAudiophile]

So no pics anymore.
Hopefully everyone is fine though.

(edit: seemed like a momentary server issue, pics are now visible again.)

Nope! You guys are jumping the gun here. No action by Admin/Moderators has taken place. Nothing deleted by us either. Paranoid much maybe?

LOL sorry Adam!

 

[pma]

pma how old are you? Nobody is independent ;-)

Re age, quite enough .

And sorry as well.

 

[Prana Ferox]

I see the pics just fine?

The wire solder to the binding posts isn't very pretty but soldering to big heatsinky posts is harder than it looks.

Some posts with massive amounts of photos like this one has, can take extra time to load up and on occasion can trigger an Approval request. The Approval requested is sent to the Moderation Team for review before it will fully publish here. It’s a website safety function and it’s automated. This may explain the delay in all those pictures being fully published/viewable. Hope that clarifies.

Now I have to run and return My Dear Leader’s (Xi Jinping) phone call!

Clean build, the ribbon cable from the TRS inputs is not going to satisfy proper audiofools though Layout looks like "TPA INSIDE" First Class LC filter components, with what I suspect is intelligent placement of Inductors. 5 Segment Pot by the looks of it? The 5th segment might be a switch. Is there a CLICK in either extreme of that pot?

All photos fine here too. Saved them here too:
