Hi everyone, I am looking for a VR-300 ,( 95 - 130 volts, 60Hz Voltage Stibilizer ) used In BOONTON Q Meter 190A. Please, If available, let me know the value. Thank you in advance! -- Renan Cysneiros There are two mailing lists that may be of help. One is the Agilent-Hewlett-Packard list and the other is the Boonton list. http://groups.yahoo.com/group/hp_agilent_equipment/ http://groups.yahoo.com/group/Boonton/ As you know Boonton Radio was bought by -hp- who continued to make several of the instruments. This is a very active list. Some of its members started a list dedicated to Boonton Radio and other equipment made in Boonton N.J. Not too active but may be of help. I suggest posting to both lists, you may be able to find a part. -- Richard Knoppow Los Angeles WB6KBL Richard- Thanks for the Yahoo groups info. I didn't know about those two. I joined the Boonton group as I have a couple of 260A's both in need of repair to some degree. Now if I can just find some time to work on them... 73, David K3KY There are probably a few people on one or the other of those groups who know the 260A well. At -hp- all the Boonton stuff was done by a couple of specialists who did nothing else. I think the 260A is reasonably easy to get operational, the 250A RX meter was a bear to get calibrated and the older 160A Q-Meter requires a special tube which was selected. Boonton liked using selected tubes, one of the 202 series RF generators used three tubes of the same type but selected for different characteristics. A royal PITA. There have been a couple of other Q meters made but the 260A is still an excellent instrument. The trouble is that most people now have no idea of what they do or how to use one. -- -- Richard Knoppow Los Angeles WB6KBL |
