peterso 寫:用海韻英國濾波環牛 la :devil: :devil: :devil: :devil:


Peter,

my 300W 海韻英國濾波環牛 broken down 2 weeks ago, and I opened it up and checked, found that the +ve and -ve output from the transformer is shorted (it is supposed to have 100v voltage), so basically the transformer is gone.

如果100v是300w的話最好用上1000w的牛牛,這樣牛牛不會太熱,同時最好有穩壓的當然對器材亦有保護.這是我少少的意見 :selfpun: :selfpun: :selfpun:
自己DIY,好過去行街........

Romrom-100Fun 寫:To every BROTHER who use 240V ---> 100V Transformer
=====================================

This is very dangerous I exprience yesterday night!!!



After the Yamaha overload this posted unit, the fuse broken!!

I change to a new fuse and try to switch on, it broken again!!

I check it with my Multi-meter, find that the curcuit was
SHORTED!! :a007: :patpat1: :a011: :a011: :a011:


EVERY brother must be careful!! :maskman: :announce:

My 600W transformer is still working perfectly for over 5 years usage. It does not have problem for use with my 150W (100V) Victor subwoofer. I also tried it with the Victor HM-DHX2 32W (100V) satisfactorily.

I wonder why yours is having fuse blow-out problem. However, I remember in the past when I plug in the 220V Yamaha DSP A1 (500W), the fuse burn out due to overloaded. Hence, I believe the transformer should have a rating at least double your equipment. Hence, for AV Amp of 400W, you should use 800W transformer for sake of safety on potential peak.

:selfpun: :selfpun: :selfpun: :dont_agree: :dont_agree: :dont_agree:

Hence, for my DSP AX-2500 (400W 100V), I use the transformer of 1,500W.

Correction: The transformer is still working, just the fuse was blown and it should be replaced with a slow-blow type (and I replaced with a fast-blow, so ...)

I also forgot that the resistance between +ve and -ve of a transfomer is very low as it is the two ends of a coil (~ 2 Ohms) and it appears to be shorted.

Sorry for the misled information. :sorry: :sorry: :sorry:
