Really pleased with the mods that I have completed to my Caiman power supply and have added a few pictures (sorry grotty flash ones) to show what has been done.
I wanted to remove the Murata Super Regs and feed new regulated "linear" supplies instead. The power supply is basically two separate supplies in one box one set at 14.5v and the other at 6v.
The supplies are:
1. Avel Lindberg encapsulated toroidal's giving a 17.5v AC supply.
2. Avondale full wave bridge kit with Schotty T0220 Diodes.
3. Kendeil 10,000uf cap.
4. Avondale pretracking regulator kit.
The 6v supply is fed to 5v Murata point and has a resistor and 220uf cap (under the board) and passes forward bang on 5v. The +ve feed from the 14.5v circuit is cut here also although the 0v grounds are kept common.
The 14.5v supply uses the existing diode and fuse route but I have taken out the 10,000uf cap and just put a tiny film in (not really needed though). Again a resistor and cap has been added at the 12v Murata position. The 14.5v input gives bang on 12v at this point on the board.
The sound, yes different to before. A step forward in smoothness of the high treble notes and more of the "blackness" between instruments. Bass is more controlled but still as deep.
Enjoyed doing the project and feel it was well worth the effort.
