Hi, I have a question about the Service Bulletins for EFJ Desk Kilowatt. I have only seen one Service Bulletin marked as such, it was Service Bulletin #3. I have not seen any other material actually marked as "Service Bulletins" #1, #2, or #4. Does anyone know if those Service Bulletins #1, #2, #4 really existed? Thanks, 73, Scott WA9WFA in Saint Paul Minn
