Title: New member: Uni 8515 power supply parts
Post by: injun46 on April 30, 2020, 06:58:16 AM

This forum certainly contains a wealth of information on slot machines. I have a Uni 8515 3 reel slot that needs parts for the power supply. I found old listings of part numbers on posts on the NLG.net website but they are also obsolete. Does anyone have current replacement part numbers for the bridge rectifiers and the 5 volt voltage regulator?
This power supply must have been worked on in the past as the 5 volt regulator has two Zener diodes on the output to the case common as a patch. All voltages at the 12 pin connector were correct except pin 8 which was 4.5 VAC measured to pin 10 which is also case common. Pin 8 also had 5.1 VDC to pin 10.
Also, another issue is no LCD displays which means that the MPU is not running. I want to make sure the power supply is OK before trying to resolve its problem.
Thanks for any help I can get.

I might have some old supplies sitting around,  removed all the fuses and fuse caps,   but I think all the electronics are there, and PROBABLY  good.

Actually Jim I tried to call you Monday morning, tried to leave a message. I looked up your phone number and found that you are just north of cinci off of I-71. Have been up through there quit often as son and four grandkids live just east of Columbus. I live in SE Missouri, which is considered the Midwest also.
Anyway, what do want for the parts?
