Description: This kit contains replacements for the electrolytic capacitors, power resistors, and bridge rectifier for the power supply sections in the ARP/Eminent Solina String Ensemble synthesizer. This is for the heavy model with the circuit boards that are in a big steel frame. The kit works for revisions both with and without the modulation button. The power supply is actually spread over 5 different PCBs in the synthesizer, not just the “Power Supply” PCB, and this kit has the components for all the voltage rails on all the PCBs. The original electrolytic capacitors were underrated, the manufacturer exceeded the rated voltage of the capacitors, which was bad news. In addition, these 40 year old capacitors have long since dried out and stopped performing as they should. This kit contains high quality electrolytic capacitors to replace these failed or failing capacitors and provide decades of stable operation. The String Ensemble uses resistor dividers instead of voltage regulators, and as such dissipates a lot of heat through its power resistors. Compounded with these resistors being lower wattage than they should be, I often see scorched PCBs, peeling/flaking paint on the resistors, or damaged and badly out of spec resistors. The kit includes metal oxide resistors with 2-4 times the wattage of the original resistors to replace these key resistors. Also included is a higher rated bridge rectifier to replace the aged original. Some key axial capacitors are replaced with radial capacitors because of their more favorable temperature and ripple current ratings. High temperature 105°C capacitors are provided for several key capacitors and voltage values were increased above the original where they will physically fit to ensure rock solid operation and long life. In this video, I explain the kit, its importance, and show it being installed in a String Ensemble that was in for repair: https://www.youtube.com/watch?v=IG4rTb70v30 This must-have upgrade will breathe new life into your ARP Omni 2 synthesizer keyboard. This pre-assembled kit replaces all 15 of your old sliders with new, smooth, high precision LED illuminated sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement. The values and taper types of the faders are the same as the originals, and a single assembly with multiple sliders is provided for each of the three PCBs in the Omni 2, to ensure that all of the sliders are parallel. The kit comes with all orange LED, but a variety of custom order sliders are be available, contact us to discuss your desired color scheme (see photo of custom purple sliders we made for a customer). While you’re working on your Omni 2, also consider our recap kit, 4075 filter enhancement kit, or a new set of key bushings, all available from our store. Please feel free to contact us with any questions regarding this upgrade for your ARP Omni 2! Installation of this kit requires disassembly of your keyboard and soldering. If you’re not comfortable doing this, we offer this upgrade with installation services, please check our store for pricing on the installed upgrade.--New eBay account, same Synthchaser you have known for years.
