Perreaux SM3 Upgrades

The picture below shows the completed upgrades. All electrolytics have been replaced. There’s 12 alone in the power supply, and many more across the pre and phono boards. Elena Silmics have been used where space permits, otherwise Panasonic FC and Nichicon Muze. None of these is in the signal path. The main input and output capacitors-originally metallised film have been replaced with foil /film types. All components were mounted as in the original preamp, with the exception of two in the phono stage which were mounted slightly above the board to allow for nearby warm running resistors.
