Bob Carver LLC Black Beauty Review

Kenster, I'm not a blood sucker (DraculA)...I think you have me confused with my ex.

If you open up the one mono block chassis, you should see two 0.22 uF caps, one for each bank of push pull output tubes. Those are the coupling caps you need to replace. Bear in mind, each mono block also has one 2.2 uF feedback cap. Leave that alone, because only a few percent of the signal actually go through that cap. I don't know what the caps look like because my amps are not the current production version. They may have switched to a different brand, but I can tell you they will be small, not big like most audiophile caps. If you shoot me a photo of the inside of your amp, I can locate them for you.

The volume control is easy to replace, if you know how to solder. It goes right before the input (grid) resistor to the 12AX7 tube.

Oh yea, I've been meaning to replace the input resistor as well. As far as resistors go, this resistor probably has the most influence in the sound. It needs to be 3.3 kOhm, 0.5 watt resistor with 300 V rating. May be a Shinkoh metal film, nude Z-foil, Riken carbon film, etc... depending on your taste.

What type of improvements does one get with these upgrades?

Gold Point Attenuator/Vcap -- Increased clarity, dynamics, low and high freq extension. Better imaging and staging. Fuller, more natural midrange. I think the GP gives you more bang for the buck.

Anything better then a Vcap to further upgrade it? How about The Duelend Cast?
