Yamaha KX-580 fail...

It's the last of the famous George's kit to look at ...

It's a mint condition KX-580 with a nasty noise on the left hand channel.

When I say mint, I mean mint... it looks like it's never seen a cassette in it's life.

Sadly I rapidly trace the fault ... it looks like an open circuit head ...

... and sure enough it is ...

Game over. It's a special low inductance GX-37 head , and utterly unobtainium. I hate being beaten, but sometimes that's just the way it is....

Disclaimer.

Many pages on this blog describe working with high voltages, and vintage equipment. Sadly in this day of litigation, and common sense being absent, I must publish a disclaimer.

WARNING. Do NOT try these things at home. Most of the equipment I deal with in these pages uses high voltage, it will floor you or kill you if you come into contact with it. It will not warn you, blow a fuse, nor pull your safety trip. It may not give you a second chance. RESPECT IT'S AUTHORITY.

Many pages describe working with mains, or dealing with mains powered equipment which may have exposed mains connections inside the enclosure. Pull the plug and isolate before removing covers! Some equipment, in particular valve (tube) amplifiers, television sets and switched mode power supplies, can store high voltages for a considerable period of time after the power has been removed, especially if a fault condition exists. Always check and safely discharge capacitors. Safety is paramount.

There is risk of exposure to chemicals and physical debris. Precautions I take include, but are not limited to, use of rubber gloves, fume extraction and safety glasses.

All material on these pages is provided 'as is' without warranty of any kind, either expressed or implied. I will not, under any circumstances, accept liability should you injure, or kill yourself repeating any of the content of this website.

Always seek professional advice if in ANY doubt.

Not a business.

I repeatedly get requests, via messaging etc, asking me to fix their kit for them. This is just a hobby for me. I don't take on repairs on a commercial basis. The idea is to give my readers an insight into what's involved, and enable them to fix their own gear, (within the realms of safety of course), and I'll always help if I can. It's really for my own enjoyment and entertainment. It all started out with a simple website to actually document what I was doing, rather than making copious notes on paper, which I'd been doing since the late 80's. It was a friend that suggested I should make it all public, so I did. I never dreamed anyone else would find it interesting, and yet, I get around 200 people visiting everyday, which astounds me even to this day. So, sadly I can't fix your gear for you. Take it to a local firm. There are still a few TV repair places dotted about, a good few repair cafe's operate up and down the country, and see if you can find a tame radio ham who may share some of their knowledge and experience. There are a few "Makerspaces" dotted around the country, and they may be willing to help. I currently work as an engineer in the broadcast industry, and, until that changes, this will just remain a hobby. Thanks. Doz.
