PP-112 Vibrator Power Supply
I'm trying to get the subject PS going. (Its from a Korean War era
military radio.) I have two of the PS plus one spare vibrator. It appears that I have only 2 good vibrators out of a total of 7. Does anyone have any suggestions about how to test the damned things and/or what to do when they really are bad? Is there a better newsgroup in which to seek help? For direct replies, my email address is cjr at visi dot com. 73, CJ K0CJ |

Replacement units should be available from Antique Electronics Supply, and there are some solid-state replacements being made today as well. They are really just a buzzer in disguise... open one of the bad ones up and see if the contacts are bad or the coil is open. Contact cleaning may make it come right back up again. Coil rewinding is no fun. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
