| ::Now that I have your attention. LOL I've been working on a Belmont 602B Freshman and it works great with the top off but when I put the top on (cabinet) it hums. Already tried goat shields but didn't ground them to the chassis. I know it is noise but having trouble correcting this problem. Anybody out there in radio land run into this problem? Thanks George T. : : Try it with the tube shields grounded to chassis. Sometimes to leave the shield float like that may pick up hum. Also check if the cabinet is isolated from the chassis, and may even have a capacitor from chassis to cabinet. : : Well I have tried pretty much everything with no luck. I'm kind of wondering if the speaker cloth might be causing it. The speaker cloth has what looks to be metal thread woven into it (gold). I sure would hate to take it all off and still have the problem. With the chassis playing with out the cabinet on it, it sounds fine but as you lower the cabinet onto the radio the hum gets louder. Weird!!!! Any ideas would be really welcome at this point. When you turn up the volume it covers up the hum. Thanks again, George. |
