no typos btw. it is 22 vac not 220

"N - L is 2.5 volts," You should have 230VAC at the L and N. Look at the back of the unit for fuse/fuse holder.

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

any idea why i get a different measurement directly on the leads compared to N - L? i couldnt get my head around it, i did several measurements

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

The two red wires go to that panel (green circuit board with red caution label) which I cannot tell what it is, there has to be a fuse some where for protection. Can I see the back side of the unit?

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

i think i found the fuse, directly at where the power cable plugs in. however i cannot see / access it because one screw of the cover is completely locked with glue. i think theres also glue around the screw thread. i will try softening it with a hairdryer.

i feel like such a newbie now.... oh god

Some of those IEC AC inlet has the fuse holder that snap in place, let me see the AC inlet.

got it open

has to be replaced

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

OK, you need to pop out that fuse holder with small flat blade screw driver, do not remove the inlet from the chassis.

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

yeah that's exactly what I did. I'll report back when I get a new fuse installed.

Budm I feel so sorry for you about the anti-climax

[budm]

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

Well, I just hope that it did not blow the fuse due to shorted circuit that is connected to that TOROID power transformer secondary side such as the output transistors or bridge rectifier.
Make sure to match the fuse type, I believe it should be time delayed (there will be letter 'T' on the fuse body) because TOROID transformer has high inrush current.

no T there

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

I am surprised it uses Fast-Blo type, especially that relay kicks in and out all the time.
So did you find the new fuse to try.

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

I can find plenty of suppliers online, but none locally, and it's either very long shipping time (China) or high shipping cost to my country. I'll continue the search...

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

I can source this one quite fast and cheap, looks like a good alternative? What do you think?

Schurter 0034.1521
It's 3,15A instead of 3A but all the rest seems similar to me.

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

That will be fine. I would think these 5*20mm will be easy to find in Euro.

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

3a is not a standard size for 20mm, 3.15a is.

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

TAGA must have their source from some one otherwise they would have put in 3.15 fuse in that unit.
No problem in the US, you can get 3A, 3.15, 3.50, ETC.: https://cdn.badcaps-static.com/pdfs/...1e9019c3c6.pdf

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

as far as i know the manufacturer is partly based in china and partly in Poland

Re: Subwoofer auto on/off: Taga Harmony Platinum SW-10 v.2

with the new fuse it works again
so I have no idea why it failed in the first place.
i'm thinking now about replacing that one resistor again with a higher value to make the sound input detection more sensitive. but i'll first check a bit how the sub is performing in the next few days.
so thanks again budm . you guided me through this very very well
