Follow-up on MC-30 Rebuild

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

I'd heard that K-40Y capacitors need some break-in time. The amps sounded great immediately after the rebuild, so I didn't "get" the break-in time thing.

Now I do. We're about 40-50 hours in, and holy cow. The thing that's most objective is that on a great recording (SACD titled "Kenny Burrell and John Coltrane [most highly recommended; great music, excellent original recording, great remaster]) instruments playing in unison are exactly that--individual instruments playing in unison, rather than the mashup most amps present.

I'd sure like to know the physics behind break-in of a capacitor.
