Re: How to test low voltage capacitors?
Craig - surely changing the capacitance would affect the functioning of the circuit? I can't say I'm knowledgeable to do more than just slavishly copy what's in the circuit diagram when doing repairs, but it's an interesting proposal.
As far as this tantalum proposition goes, I've replaced all on the playback amplifier and the difference is night and day on the headphones. I won't use any of those 'audiophile' terms, but where the sound was before 'fine', it's now 'very good'. No muffledness or the hisses and crackles that there were before. Considering the tantalum C316 was the cause of the channel failing, I'm happy to believe the others were not too happy after forty years, even without the ability to definitively test them. I'm a bit sad I haven't any wet slugs though. Better search in the garden... |
