Wow now that's some modification Promethk! I like to swap out the tube quite a bit so I run my Havana topless as well. Xcel built a 2 million dollar substation a 1/2 mile from my house so I'm not going to get into the AC line conditioning issue. What value output capacitors are you using? I'm thinking about picking up some 2.0µF / 200VDC Gen I Sonicaps to start with. The battery mod will have a miniscule WAF, so I'm stuck with AC.
I second that.
To be honest ... I have no clue as to what the intention of that posted bit was in regards to sonics ... but I know he wouldn't run his DAC half taken apart if it didn't result in *some* sonic improvements.
I too am tossing around the idea of a significant CAP upgrade on my havana ... but I'm just not sure which, if any, of the MHDT produced CAPS should be replaced.
Was thinking Mundorff, Blackgate or Sonicap ...
Just not enough info for mod n00bs like myself to make me take the plunge, yet.
