Sublime Subwoofer Amplifier kit / Re: A working amp went silent

« Last post by ipetruk on July 09, 2025, 08:59:13 AM »

There seems to be plenty of the XH-M311 power amps on Amazon, cheap.

I'll get one, for example this one: https://www.amazon.com/dp/B0822RDW6J?

Are they all the same provided they are XH-M311? Or are there kinds of it?

I think the issue is the power amp. Plugging in high impedance headphones directly into the preamp output and gradually increasing volume produces a mumbling sound, consistent with what is expected of a subwoofer filtering.

Sublime Subwoofer Amplifier kit / A working amp went silent

« Last post by ipetruk on July 09, 2025, 07:24:47 AM »

Hi,

I enjoyed Sublime amp with my subettes for a few months. It worked very well, super happy with it.

Now it went silent. No hum, no sound. All LEDs are on. What I have tried so far:

1) Re-do checks according to the manual. The readings seem to all be in order. This should imply that at least the power supply is ok
2) Eyeballed all solder joints and checked the wires
3) Replaced Sublime with a different sub amp, keeping the same input and output wiring. It worked, so it means the problem is not in the rest of my setup.

Is there a way to further test it? Or is there a way to narrow it down to preamp block or the power amp part?

Thanks,
Igor.

Are there really that many components? I never noticed.
Your next assignment is counting the number of parts in a Kaiju kit.
OK, now count out 5 more.

I think it was around 415 components until you include some of the things you might not think about like bells and tube boxes and different lengths of wood.

I might count all the Kaiju parts to help me get to sleep.

We are making progress on the 400+ components in inventory and are feeling like we can start keeping things in stock more regularly. That means we have many kits and upgrades - including Moreplay Upgrades - in stock right now!

Moreplay / Re: Moreplay Upgrade Finished

Here some tip.
 For the heatsink.
Inner one, install the chip on the heatsink, solder the heatsink to the board tight the screw that hold the chip.
outer one do the same. this way there is not stress on the chip legs.

The signal cables in case are short I passed under the balance pot this way there will be enough cable for soldering.

I holder all the filters together with foam in between and a zip tide.

I was trying to post pictures but its little challenging.

Thanks again Paul.
 I measured the PT and read 55 degrees C ~ 131 degree F dont recall how much was before.

The volume knob now play at 9 o'clock decent sound instead 7 o'clock as before, but there is better control at low volume for sure.

Andre.
