    Bad new cap

    I have just repaired a valve radio that need a new capacitor. I replaced it as it had gone open so I put a new one in only to have it go pop some 2 minutes later. I found that the case had a resistance of only 23 ohms to one of the pins.
    Not good at all.
    Have anyone else seen this?

      Re: Bad new cap

      Did you put in a New Old Stock capacitor or a new modern capacitor?

      If the former, you may have needed to reform it before using it.

      If it's the latter, it probably was either over voltage or reverse biased.

          clock radio / radio lifespan?
          by shelby5041
          hi
          ive got a modern digital clock radio approx 15yrs old

          my question is how long can a clock radio or a simple radio last ss farcas operating hours?

          since elec components have limited hour lifecspan i would imagine the radio or clock radio would eventually fail.

          the reason i ask is because i have my clock radio on radio function 24/7 for the past 7 years and its still working fine....i leave the radio on ..never turn off past 7years...thats approx 60000 hours

          it uses very little power just a few watts i would imagine that may have something...

          Schematic vs. Reality: Where Are the Resistors on My Sharp Clock Radio? Model FY-70CH
          by TinkerTron
          Hey everyone,

          I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.

          Instead, here's what's been bugging me so far:
          The schematic...
