Good evening. I have been persuaded to try here for (substantial) help in repairing my trusty 505 rather than replacing it. I can just about handle a soldering iron but otherwise I'm totally new to this...

The only thing I can tell you is that, after several decades of service, all I get now is a loud and unchanging 'hum' when I turn it on. On all three bands and any position on the dial.

I've taken the board out and there is nothing obviously amiss to my unskilled eye. But it looks complicated in there..!

Any clues?

Thanks,

Tim
