you can use an MC1350 to amplify that signal, in case of absolute necessity. It has the advantage that its gain can be set with an external resistor, and the IC is really cheap.
Hello Stefan, I se you have a HP counter is it a 5340A, i have a 5340A working so if you need to service your sometime you know where another is, if you need any measured values.
Hallo Stefan, den LM703 habe ich damals nach dem Vorschlag von DL4CS nachgebaut. Aber sicher hast Du seinen Vorschlag schon beim Googeln gefunden. 73 Bernd
A very funny movie to watch, but not so funny to live! I checked my bench stock, but no 703s to be found. You might look at the TI THS4130 or THS4131 as a substitute (with a small adapter board), around $8 US from Mouser or at your favorite supplier. Regards, David
