Hi,

don't give up, gc339 has done a fantastic work, thanks to him i was able to repair my pcb.

if i can give you a advice, don't forget to replace your olds 78L15 and 78L05. These little bastards are voltage regulators and i think they were the cause of massive damage on my board... 

good luck !

Hi

Thanks for the info - I will also order those then and change them just to be sure.
I refuse to give up, and not after that i found the guide from GC339 I hope that i am able to get the one power supply fixed.

Kind regards

Hi

Thanks - Ill order some of them that shoud be the last compnents that needs replacments
(with my basic skills to identify them)

Then i hope that i have found and replaced all the defective components, so when i turn on the power nothing blows up

Hi

Fist of all sorry that i write in english in a french forum, but it is the only forum that i have found where there is a person who might be able to help me with my Sega Gloc power supply.

I have read this tread http://www.gamoover.net/Forums/index.php?topic=28660.0  abaut restoring a PSU for a sega gloc deluxe - and first of all I am impressed!!!

I hope that "GC339" is readin my post because i would like to ask for his help (if possible)

So now to my question - I have also a defective PSU and i have changed some components, but there is a resistor that i am unable to find on ebay.

Its abaut 2 cm long and has legs almost 1mm - The color codes are Red-Red-Gold-Gold
If i type the color codes into a resistor calculator i get 2.2 Ohms 5%

But all the resistors that i have found physically smaller in size.
I do not know the voltage of the resistor, i assume that it sets the size of the resistor?

I have attached a photo of the resistor that I need - then i hope that you can help me identify it.
Also attached a picture of the place where the resistor is located.

And last i with that i where just as smart as "GC339" or that i lived in france and not i denmark
