SR-52A rebuild project (SR-52A 942058 LTA4176)

[albertofenini]

Hi Jose

thank you very much for your message and your support

I had read all of the thread when I started to restore the two SR-52 that where complete and running
Those two units S/N 953114 LTA4176 and S/N 014131 4775DTA are of the same version of the one you have
pictured in your post, card reader is attached to the main board on the upper left corner (component side) of the PCB
What kind of version is this ? SR-52 or SR-52A (just to know)

The service guide you mention is the "SR-52 and SR-52A troubleshooting guide" ?
If that is the one, I have it and I have read it throughly, still I couldn't find a reference to Q4

These other two units, which I had dismantled almost fifteen years ago, and of which the working status is unknown ,
are however of a different type, they have four green capacitors in the upper left corner and the card reader
is connected closer to the battery terminals

   

These units S/N 942058 LTA4176 and S/N 086513 LTA5176 with the green capacitors which version of the SR-52 are ?

Also I looked in the Etienne section of the post but I'm afraid the links are
expired, images won't load and the link referenced is not working

What am I missing ?

Thanks for help !

The information I gave you is taken from the SR52 service guide that I bought on eBay long time ago and later I made it a available to all community thanks to Katie.
Please see the schematic diagrams for both versions of the 52.

I dare to link here to my own findings at the time, hope that this action will not be censured here as it was in the past with another project of mine.
Please browse the pages until you see the link to Katie's website where the service manual was uploaded.

Gene's thread hijacked by me on the SR-52

Wish you good luck with your project.
I didn't quite restored my SR-52 as other tasks were taking my time until I forgot about it.
