OT: Weird Kenwood Receiver KR-6030 relay problem

[rob]

Hello,

I have "normal AM/FM type" Kenwood tuner/audio amplifier Model KR-6030.  It outputs a big 80 Watts per stereo channel.  Not wanting to pop your speakers as soon as you flip it to "ON," it has a time delay relay that lets the speakers get connected about 10 seconds after you flip it  "ON" and by then circuit's capacitors have settled down etc.

This thing never turns the amplifier on if the weather is humid --- just never kicks in.  In the winter, or when it's extremely dry, it does kick in --- sometimes.  Weird thing.

I can always "force" the relay to kick in (connecting my speakers properly) by taking a hair styling-type blow-dryer and blowing it on to the relay ---  as best I can through the cabinet vents.  Then 10 minutes later or so, the things starts working.

I mentioned this to friend at work and to my amazement he noticed the same thing with another radio --- he has to get out a hair dryer to make it work if it is on a humid day.

Has anyone else has this problem, and do they know how to fix it?

Thanks,
