Post subject:  Cap replacement - off topic

I was wondering what is a suitable replacement for tantalum caps on old synths etc.

mostly they are 10uf or 1uf. I replaced the 10s with electrolytic and am thinking of using monolithic ceramic caps for the 1's as they are about the same size and lead spacing.

these caps are all power supply related, not filter or timing.

Hey PaiaBill!

imo, tantalums usefullness are over hyped/overrated. For power supplies, electros are just as good as tantalums. Electros might be a little larger for the same capacity and voltage, but, don't think size is an issue in PAiA stuff. 10mfd is 10mfd. In stompboxes, folks like to replace 1uf electro coupling caps with monolythic. Claims of "sounding better", but, I think, that is more subjective than objective. On my scope, frequency response is frequency response (the same). So, I think U are fine on both counts. But, don't replace anything unless U see signs of leakage or swelling. U know, if it ain't broke,....etc etc.
Have a PHantasticPAiA day! 8-)

I think it would be prudent to replace all the tantalums to prevent future 'tantrums'

since shorted caps tend to blow power supplies I think it makes sense
