SoZo Royal 67 Capacitors™
SoZo's single 100uf radial electrolytic super cap is named the Royal 67. It is modeled precisely after the vintage Hunts™ / Eire™ / RS™ capacitors found in the 1967/68 10xxx and 12xxx series of 100 watt Marshalls. It is called a super cap because of its amazing ratings; modern electrolytic capacitors are rated for 2000 hours, the SoZo Royal 67 can operate for 10 years straight - 87,650 hours. It is a standard 1 3/8" diameter so it can be used in place of the 50x50 capacitors found in the later Marshalls.
Warning: Guitar amps carry lethal voltages and discharging the amp prior to installation is absolutely necessary! If you are not a qualified technician, we recommend that you find a qualified technician to service or replace these capacitors. This cap is only 350vdc rating like the originals. It is intended to be used with 100 watt Marshalls in the voltage doubler power supply. Two capacitors are used in series to equal 700vdc capability. They can also be used in the screen grids and in the phase inverter section where there is less then 400vdc surge.
