I can find no information on the GED04 transistors below. I scoured several GE manuals 1971-1977 and found no mention?
Hoping a savy chap can identify these and point me to a data sheet.
I found the T1006 crosses to NTE102A.
Regards, Doug
Besides tracing the ac/dc to determine switching and control paths, Im having trouble identifying 2 components.
I've looked through my ge manuals and couldn't find these part #'s.
printed on the semiconductor is GED04-32 / GED04-34
Can you identify these parts?
Q2 & Q3 I have nos replacements...
Hello Jeff,
Your reply is off the mark, The issue is not about DC circuit for welding.
The image I posted above is a small rectifying circuit for current control on L5268T and I believe there is an ac component along with the dc that powers the pulse transformer?
This is not the larger bridge...
having a tough time understanding the circuits.
The ac & dc share paths and then travel into separate circuits?
I have 2 boards, the original and a replacement, both suffered damage from a shorted remote cord.
If I could understand the how/where the current travels, troubleshooting would be much...
Hello,
I don't have a background in electronics, but have always been interested in learning more and I found this forum hoping there are some folks looking in here that can shed some light on the control board I'm working on.
The board is from a 1974 Lincoln welder, I'm restoring the machine...
