![]() "Fred" wrote in message om... I would like to build a VFO for a CW transmitter using any type of vacuum tube. Can someone help with a schematic? Thank you. 73 wb6iiq / dh1nwr Fred - You can also look at proven designs and schematics Drift is an issue with tube based VFO - and regulated power supplies are recommended. Many schematics and manuals are available at BAMA Such as the Johnson Viking VFO-122 http://bama.sbc.edu/ Here is another web site for schematics http://www.geocities.com/CapeCanaver...1/hamfiles.htm w9gb -- Do not use Reply.
