Capacitors for BAT VK-60

Sherod,
Going on what Dgarretson advised.

Viewed through the side or bottom cover, you’ll see four 2”L x 3/4”W yellow/green caps across the PCB beneath the 6C33C tubes. The caps are marked Balance Audio Technology ..22uf/630V. They can be desoldered without removing the main PCB, and replaced with four V-Cap TFTF .22uf/600V. When installing the V-Caps, face the red lead to the rear of the chassis and the green lead to the front. Put a piece of Radio Shack double-sided cushioning tape between each cap & the PB.



Allow at least 100 hours before critical judgment and 400 hrs for full break-in. But I think even cold out of the box these teflon caps surpass the stock paper-in-oil BAT/Jensen caps. This upgrade simply transforms the amp, particularly in terms of improved bass control & dynamics & elimination of sluggishness. The caps sound continuous, detailed, airy, very real & very musical. No down-side whatsoever once they’re broken in.

Flemke - You installed the V-caps on 4/30. On 5/3 you report back saying that there is "no downside whatsoever once they are broken in" and that they need 400 hours to break in. Is that comment based on your experience? How did you get 400 hours on them so fast?

Rgurney,

As Flemke mentioned, those are my comments, reflecting V-Caps at 160 hrs in a VK75SE.

Who's amp is in my basement? It looks like my VK-75, but sounds about 3 levels up in performance. I have about 50 hours run time on the V-Caps. If you own a VK amp like the 75, I would strongly suggest doing this 30 minute swap-out. Go read all the comments on the V-Cap web page. They are all true. Sorry I don't go into details, it's all been said on the TFTF site.

Ed Sawyer,

I have tube rolled some very nice old stock 6sn7's.
None of the changes were even in the same ballpark of the V-Caps.
