I performed a complete restoration on an early model 89 recently.

In an effort to put it back into it's original configuration I removed the 6Q7 and the associated octal socket that someone had installed to replace the 75 2nd detector. I also incorporated the mods that are described here.

The radio works great in my shop but when the fella takes it to his house he says it makes humming/buzzing noises while on station and between stations. I can't reproduce this problem except by touching the top cap of the new 75. It's hard to understand what people are saying when they try to describe a problem. Whoosh, clunk click, click etc.

I've got the radio back in my shop and there's nothing wrong with it. I'm wondering if when the original 75 socket was removed the shield holder was also removed. I don't know this for a fact.

So I'm asking if the 75 2nd detector was originally covered with a shield on this radio?

Thanks,
Pepper
