Thanks to the generosity of Chuck Harris in loaning me a manual, my HP 107BR is now back in service, or at least warming up back to a stable state. Shorted Zener diode (CR2 32 volt) and burned out series resistor (R1) replaced and all OK again.
I have made three extra Xerox copies of the manual (2 side to 1 side, double copies of schematics), that are now available to whoever needs. Please advise. 73 Les K1YCM/3 Full Name: Lester B Veenstra Job Title: Computer Sys Des Engr Sr Stf Department: 6L01 Company: Integrated Systems & Solutions Business Address: 133 National Business Parkway Cube 224 Annapolis Junction, MD 20701 United States Business: 240/425-7335 Mobile: 240/425-7335 Pager: 240/425-7335 E-mail: [EMAIL PROTECTED] -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Veenstra, Lester Sent: Thursday, September 15, 2005 9:30 AM To: time-nuts@febo.com Subject: [time-nuts] RE: HP 107BR > I have a problem with my old faithful standard, an HP 107BR.
