This may seem to be a simple question but I have a 100th modulator tube that has a intermittent filament pin. I have resoldered it a dozen times and it may operate for 2 weeks or 5 minutes. Its in a BC 610 that I have just redone and have had it on for about 2 weeks. the tube is a new or nos. Is there a special type solder that would be better to use than just regular radio type solder Bill Fondren K5PML

Have you swapped the 100th's to see if it's the tube itself? 73 Brian / w5ami ______________________________________________________________ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected]
