<br>
Slightly off-topic, but I am re-capping an old (circa 1977) MXR Digital <br>
Delay and am wondering about the numerous small tantalum capacitors that <br>
are in this unit. Should I leave them be? Replace them with new solid <br>
tantalum parts? Replace them with some other technology?<br>
<br>
Unfortunately the replacements need to be through-hole parts, which <br>
rules out some of the whizz-bang technologies touted as tantalum <br>
replacements, such as niobium oxide.<br>
<br>
Thoughts?<br>
