fyi, 2sc5200, 2ca1943 absolutely fake if the part number can easy to read. i bought in eleshop raon. when I powered it to my amp my fuse blown. just for curious I cracked it and I found that the die is undersized.

there is one transistor the part number is hard to read, but no idea if it is genuine. according to the store (eglo electronics supply) it is original daw. I dont think so the price is cheap php 90. huh

rlg ;) ;) ;)

I have been looking in eleshop several times and have not bought any output devices yet. but I have asked them and they have two types. toshiba and fairchild outputs both 2SC5200 and 2SA1943. they are selling the fairchilds at higher price probably these are originals?

So far, the parts I got from Alexan, Deeco, Orient are working good. As far as I know, original power parts are laser marked. Another criteria if a part is fake is its wieght. We can compare it with the datasheet.

hello heinrich,

I the pro8001,8001,9001 which one should i mail to you?
The original Toshiba 2SC5200,2SA1943 has a golden brown marking that can be easily rub off and the metal die is not so shiny. I got mine for 90 pesos each.

Best Regards,
audiomachines

ok lang, medyo busy sa work...malamig na sa umaga at gabi dito pero sa november pa ang snow:D

balak nilang magclone ng high powered amp sa thread na to, baka makatulong ka sa pag-layout ng pcb?:D

@all,

ferds can help you lay-out a professional looking board for a professional amp using protel software, we can do a group buy of boards from a pcb manufacturing house. FYI, i participated in a group-buy for leach 6 transistor amp and cost was U$11, not bad i would say....

xaudiox 29th September 2006 02:10 AM
