    LED Edison-style patio lights

A problem with the second string would cause the third to fail etc. The fault would appear from the blown bulb onwards. This...

    NAD 3020A Amplifier Low Volume

    What’s that three legged component next to C637?. Just above the transformer in your last photo. It looks rather malformed. As previously said, ALL the electrolytics should be replaced as a matter of course. During the 80s, many companies used glue for components which did indeed prove to turn...

    Woo-Woo Infrasound and leaky feeders

    I think somebody’s spying on you and have hidden transmitters in your walls. All you need is an RF bug finder. Remember that the human head is also an antenna, so place foil over your head while bug hunting. Martin

    30A LED dimmer will not work for controlling electric throw?

    I agree with your last statement. Is the 'throw' resistive?

    Iwatsu ss-5711 probe suggestion

    Surely any 100MHz probes will work. Have you read the manual?. http://manuals.repeater-builder.com/te-files/MISCELLANEOUS/IWATSU SS-5711 Instruction.pdf Martin

    PURE Chronos CD No volume

    Is it buzzing from both headphones and speakers at the same time when headphones are plugged in?. If so, the jack is suspect. Martin

    What music do you like?

    I can!. Not my type of music at all. Not even dinner table background music. Sorry. Martin

    PURE Chronos CD No volume

    Is the headphones jack a standard 2.5 or 3.5 stereo jack?. These normally have a ‘switch’ via a metal link that opens or closes the circuit. Can you see and verify this is actually working and is contacting either or?. Martin

    Graphic equalizer

    I don’t see any reason why you can’t install 4 RCAs on the back panel. But also make two Short RCA/phono leads for bridging in case the EQ should fail in the future. Martin
