Just finished drilling this one and shooting the video. I should have it up later today or by tomorrow. I'm Midnight Audiophile on YT.

I'll help you out with getting it drilled. I'll send you a PM. My channel is Midnight Audiophile. I haven't posted any videos yet but I have several in the works and plan to keep them coming. Thanks!I can t find you on YT...

Love NYC by the way. I went to school at Pratt in Brooklyn in the 80s.
Well, we're solving that. It isn't garbage though... Drilling a set of holes isn' t that hard really. For some of us impossible... But thankfully there are a scant few who can help. Even if you have to do it yourself. My A07 is doing quite well. Powered well, cooled even better. Follow our lead and modify this desktop beast.It appears the Chinese haven't worked out that extruded fin heatsinks don't work when placed horizontally and particularly, when placed in a sealed box with no airflow. There's no hope for these absolute idiots.
Anyone who buys this garbage deserves exactly what they get.
Did you see my post on the forum, DIY logarithmic volume. Stil have some laying here if you are interrested.Maybe needs a logarithmic volume control?
A lot of work and exacting work at that... I like the idea, but for such an inexpensive amp that's never overheated on me at 50V seems excessive. Mind you, I keep my place at 71 degreesInstead of drilling has anyone tried using a block of aluminum(solid or square tube), or a heat sink on its side that connects directly from the chip to the case? If the tolerance is right it could touch directly and transfer heat to the case via some thermal paste. A finned heat sink could then also be glued to the top of the case with thermal glue if desired.
I am considering this for my A07 and for another custom 5 channel tpa3116 setup that I am building.
Thanks,
Rich
Now that's how you holify an alu case!Just finished drilling this one and shooting the video. I should have it up later today or by tomorrow. I'm Midnight Audiophile on YT.View attachment 221262View attachment 221263View attachment 221264
For me the block just had to be 1" tall... I had some 1x1.5" stock from another project so I cut it to fit in the case and drilled two holes and mounted it.A lot of work and exacting work at that...

That's just nonsense, John. The heatsink works to transfer heat from the amplifier chip to ambient air in the enclosure, that air transfers heat to the enclosure, and the enclosure outside surface transfers heat to ambient. It's not the most direct process, but there's also not that much heat to get rid off, maybe at most 10 Watt? (100 W amp, 90% efficiency)It appears the Chinese haven't worked out that extruded fin heatsinks don't work when placed horizontally and particularly, when placed in a sealed box with no airflow.

(And I do know it's an old thread, but generalizing comments like that are just aggravating.)
If that was true, it wouldn't have the heat problems as would no other amp (like Topping PA5).That's just nonsense, John.
