Jojo, I heard the AMP you made for Doc Geriboy and it made my speakers sing beautiful music! Amazing!

Brader Jojo, will performance improve if we replace Lightspeed's supplied psu with this one?

Regulated Linear PSU for DACs, NADs, MFs, phonopreamps, ironman, batman, etc...

Good job brader Jo! pinag-uusapan lang namin ni brader Joey a couple of months ago na sana may line of linear PSU ka para hindi na kailangan pang umorder out of the country. Ang hirap kasi dun bukod sa mahal ang shipping duties, yung hassle pa of sending it back for warranty or repair. E kung sayo oorder subok na very good quality, maasahan pa sa panahon ng pangangailangan

Brader kumustamos?!

I've designed the psu of my LS projects to be stiff and quiet already, it should be fine as it is. (Menos gastos pa brader)

However, redundancy is not a bad thing either. Honestly, I haven't tried it personally so I think an experiment is in order, you made me curious how the LS will respond to the linear tracking properties of this psu.

Thanks brader! Oo nga eh, it has been in line for ages na pero sadly my sched is not that flexible these past few weeks. Yup, warranty is not a problem with us, lately time ang problem ko hahaha!

What actually pushed me to go through with these projects is the death (and explosion) of my DEQ2496's power supply. It just blew up when I switched it on. Curse those smps power supplies!!!

It was a really sad sad sad day for me... Oh well, sabi nga nila, pag may namatay... may nabubuhay... diba Cal? San na ba si brader Cal? Yan mama na yan nagpapasaya sa akin pag sad ako eh...

Sakit talaga ng mga smps yan, lalo ngayon puro made in china na.

I will surely get one or two of this LPSU in the future for projects

Will contact you soon. Bad experience with PSU shipped from China. Items got lost in transit. Apparently seller will replace BUT has not been replying. Lesson learned

Nakupo! isa pang risk yan when ordering online. Kaya it's good now that we have LPSU locally available from brader Jojo

Ewan ko ba brader, every time na may plug in ako na alam ko naka smps napapaisip ako.

Eh sanay na ako sa mga pumuputok...

Pero napapatalon pa din ako pag ang lakas ng spark!

Buset yan mga smps galing ng China, may built-in firecrackers sa loob...

Uy bad trip yan bro, with today's technology they still lose items in transit.

Dapat isama sa marketing yan - free firecrackers inside!

Sarap gamitin sa New Year celebration haha

Yup. Kakahiya nga sa isang fellow member natin dito. He was expecting dumating yung order niya. Good thing di ko pa sya siningil muna though I paid in advance. I am demanding a refund or replacement BUT di na sumasagot. Hard lesson learned

Tutubuan ka ng nerbiyos sa katawan diyan brader... a few days ago naman yun charger ng cell ng anak ko exploded while he was plugging it. Buti na lang di siya nasaktan, kaso may nerbiyos na tuwing magsasaksak ng charger!

Dapat pasabugin ang nag design nito eh.

Deym, meron talaga iba na yun responsibility nila stops once they shipped the item. Hope you get to resolve this issue.
