ESR GOOD & BAD CAP Equivalent Series Resistance - I REPAIR AMPS

[CraigRison]

The lower the ESR (equivalent series resistance) the better the quality of the cap. An ideal cap woud have 0 ohms ESR.

I've now included this info in the main description also, along with a good link to ESR details.

Thank You

Ive been considering getting an ESR meter to check caps in vintage tube guitar amps.

Would you recommend this?

I'm pretty damn confused by all this, is a high ESR a good thing or is a low ESR a good thing or does it depend entirely upon what type of capacitor you are testing? How do you know what is an acceptable level for a each different type of Capacitor you test? I recently bought a Peak Atlas Component Analyzer which gives me Capacitance and the ESR level in Ohms but!?? I had one Capacitor on a Main Board for an LCD Monitor give out a level of 63 ESR and another that gave out only 2 ESR. Help!
