| Restoration procedures "Purist by nature, obstinate by choice." There are 2 phases in restoring Vintage gear. (at least for me) Electrically: When working with vintage audio gear I follow a simple process involving first visual chassis and component inspection followed by Ohm measurements. After all the tubes have been tested and charted they are reinstalled in the unit for further testing of the unit. All equipment is brought up slowly using an industrial variac. The all critical amperage is monitored throughout the power up stage. If the original capacitors can be reformed properly I leave them in the unit. If capacitors have to be replaced I use vintage NOS when I can. Sometimes it is not possible to find original replacement parts so newer parts are used. All equipment is then "burned in" ( I love that term) for a minimum of 5 hours continuous use and then goes through several "cold starts". Cosmetically: Grunge and dust are removed from equipment as carefully, and minimally as possible. The original finish on metal and wood surfaces are left in their original state when possible. If refinished it will be duly noted. At this point the equipment is ready to go to a new home where hopefully it will be appreciated and preserved for the next generation of audio freaks. |
