[Amps] Building an Amp 101

[Ward Silver]

A good source of excellent cabinets is surplus or junked lab 
instruments.  Not necessarily electronic instruments - chemistry, 
medical, or any large instrument enclosure will do the job.  These are 
made of superb materials and would cost hundreds of dollars if purchased 
new in single quantities.  You can find them at hamfests, surplus sales 
outlets, sometimes even second-hand stores.   Ask your club members to 
see if one is sitting in a basement or garage. Strip them to the metal 
(and save the various useful bits and pieces) and you'll have a fine 
amplifier enclosure.  Cover the front and back panel with a sheet of 
aluminum from some other scrapped device - such as microwave ovens (see 
Jan QST) - and you'll have a good looking piece of equipment.
