I vaguely remembers someone said there is... but NOT for the 'local' market... hence the absence from local scene...

Not sure this is the right place to post this question, but I'm looking to buy some soldering gear.
Question: How much do the Hakko Presto 20-130W soldering gun cost in Malaysia? I have seen on these pages going for around RM75-85 yet the shops are asking for around RM50. Which is the correct price? I also read there are fakes going around? How does one not get cheated? Thanks in advance. |

I got mine for RM58 from a RM65 displayed price tag.
There are look alikes but with a different name and much lower price tags..

It's not the ones with different names and prices that worry me, it's the one with the same name and same price but isn't. Can I get replacement heater elements for the Presto? Howsabout Antex irons? Are the replacement tips easily found here? Still skint This post has been edited by totally_skint: Feb 26 2009, 09:02 PM |

Not at all.
I know the feeling. Buy from 'reputable' outlets like the Pro's Kit shop and MAPLIN from Jalan Pasar. Given the choice, the Antex will last you a long time! I had an Antex once when I was in the early stage of my hobby. Honestly I have not seen any replacement heater elements.. maybe the shop have it, a matter of asking I guess.. I have seen tips for the Antex though... QUOTE(totally_skint @ Feb 26 2009, 06:42 PM) |

I got my C2240, k170 plus a host of other transistor from Maplin. I was surprise to get those component from Maplin. However they dont really have the 556B.
Maplin also have Bennic. Wonder if it is the real stuff or not ? This post has been edited by ccschua: Feb 28 2009, 12:10 AM |

QUOTE(jazzy939 @ Feb 28 2009, 09:29 AM) I'm very wary of "fake" transistors nowadays from Pasar Rd. Already there's fake caps. It does take some experience to identify them and hints can be googled. Fake power transistors on the output and fry your loudspeakers. Just be careful.A very recent visit to Pasar Rd and I was taken aback to see many Hakko tools have increased in price. I think Proskit (supposed to be budget tools) have also seen price increase to somewhat rediculous levels. Something is very wrong going on...especially at this time when everyone harping on economy no good. This post has been edited by bsl555: Mar 2 2009, 01:08 PM |

quite true. a lot of items on partsconnexion are on sales. fake transistors burn the speakers, I guess not on mine.
------------------ Finally I got the transimpedance circuit going. Time to see virtual ground in action. hope against hope. ![]() This post has been edited by ccschua: Mar 9 2009, 12:31 PM |

However they dont really have the 556B. the real bennic cap being use by B&W in their Naulitus range.....still people consider bennic is the most entry level poly caps from all audiophile brands available....i let this to each individual to evaluate. but i'm also puzzled and keen to know whether it is the real or fake....??? Maplin also have Bennic. Wonder if it is the real stuff or not ? last time a friend showed to me how a fake JP Rubycon capacitor look like...and it just as same as the real one except the size is much much more small and it says...."Rukycon" This post has been edited by gabanyayaya: Mar 9 2009, 10:50 PM |
