I am re-chipping a Rane AC23B, and the PS is getting UF4004's and Silmic caps, both ahead and behind the regs. It's a small amount of re-soldering whilst under the hood anyway...:)
cheers,

Hope you like the Silmics. Since you are changing two things at once you won't be able to tell exactly what they are doing but they sound, IMO, very much like their description from Elna. Excellent timbres and full bodied, deep bass. What made you choose the UF4004 over soft recovery (IXYS) or Schottky? Tweaker

The UF4004 choice was for the most part an ease of replacement/board choice. It works pretty well with 1N4004, so I figured the faster diodes would be worth enough to justify the replacement. Did not feel like going Schottky shopping either...LOLThe chip set in those cross overs is rather curious. The performance of the various frequency final chips is different. The biggest shortfall is the 2058 4x chips; they are getting swapped for 2060's...and the TL072 input chips will go to OPA2134's. Am going to eliminate the output couplers too; the DC offset is trivial, compared to headroom/operating point of the following input stage of the amps. Coupling through 'lytics appeals to me not at all...LOL
