SAMS PHOTOFACT IS THE BEST OF THE BUNCH. IF YOU CANNOT FIND A PRINT VERSION, SAMS OFFERS E-FACTS. YOU CAN PURCHASE AN E-FACT AND DOWNLOAD IT. THEN YOU CAN PRINT IT OUT. THE SAMS WEBSITE HAS A SEARCH FUNCTION THAT WILL SEARCH MODEL AND CHASSIS NUMBERS. SO FAR, EVERY TIME I LOOKED FOR AN E-FACT, THERE WAS ONE AVAILABLE. THERE IS ALWAYS THE CHANCE ONE WON'T BE AVAILABLE. IF NOT, MANY OF US HAVE SAMS FOLDERS. WE CAN SCAN OR COPY WHAT WE HAVE.
WALLACE'S TELLAIDES ARE ALSO A GOOD SOURCE. DEPENDING ON THE MANUFACTURER COVERED, YOU MAY JUST GET A SCHEMATIC, OR YOU MAY GET TUBE LAYOUTS, CHASSIS SHOTS OR OTHER INSTRUCTIONAL ITEMS. THIS IS ALSO A GOOD SOURCE.
SERVICE MANUALS FROM THE MANUFACTURER IS ALSO GOOD. I FIND THAT RCA IS VERY STINGY WITH CHASSIS SHOTS AND TUBE LAYOUTS. WITH THE RCA PERSONAL PORTABLES, YOU NEED BOTH THE SAMS AND RCA MANUALS. THERE WERE DIFFERENCES IN THE VERTICAL SECTIONS AS THESE SETS WERE MADE. SAMS COVERS THEM ALL IN ONE FOLDER, BUT THEY DO NOT REFLECT THE CHANGES. IF YOU CAN GET MORE THAN ONE SERVICE MANUAL, GO FOR IT.
