How can I find out how old my amplifier is?

Capacitor values have changed slightly over the years due to changing manufacturing standards. In some cases, 5uF has been replaced with 4. Many 20uF and 25uF have been replaced with 22uF. On Ruby Gold capacitors in our standard kits, the polarity of the capacitor is indicated only by an arrow on the side of the capacitor which points toward the negative end. On Ruby Gold capacitors, both ends of the capacitor are “dimpled”, so you cannot determine polarity that way. Especially in the “silverface” years, the internal designs sometimes do not correspond with the schematic for the particular model version shown on the tube chart. It is recommended that the values of the filter capacitors inside the capacitor housing beneath the chassis be checked and verified before ordering a specific capacitor kit, to make sure that your amp was not one that did not adhere to the schematic. Always unplug the amplifier from commercial power, and discharge all filter capacitors before working on the amplifier circuitry. If you are unsure about this procedure, we strongly recommend that you leave your amplifier in the care of a professional service person. See the complete model cross reference.
