I am new to this forum. One of my customers suggested that I check it out. I - MANCO - am the exclusive distributor for Penny & Giles faders and fader parts in the U.S. Specific things that might be of interest: Parts and P&G silicone lube oil for P&G faders, Replacement slider assemblies for crossfaders with broken knob brackets, An application note on designing with motorized faders, Articles on cleaning and refurbishing faders, and Rotary faders for studio monitor level controls. I am a design engineer. I have worked with P&G faders for 20 years, including the design of the motorized fader, servo system, and much of the packaging for the Flying Faders fader automation system. I am also the originator of the 3M M56 16-track tape recorder. Please feel free to contact me directly if I can be of assistance. Minimum order for P&G items is $25, and payment is by Visa or Mastercard. For small U.S. orders, add $5 for Priority Mail shipping.
