Bob, what do you mean by better HF ? Did they use the tants. particularly for that reason and will the synth perform not as well in case I replace them with 1uf electrolytes ?

I know that Oberheim used to have two versions for the same synths, one used tants in the PS while the other used electrolytes, was that by design ?

Thanks !
