15) 2.5A 117V AC Variac
Description: Vintage Audio equipment, especially tube equipment is best tested and re-vived by applying power carefully and very slowly. This unit plugs into 117V AC and allows to regulate the applied power in it's voltage form 0-117V AC. To simply plug equipment into the wall outlet that has not been used for decades very likely destroys it and even may be dangerous - so use a VARIAC! (Variable AC power Transformer). This Variac is rudemetary and in it's condition should be completed and definitely used only be used by experts who know how to handle high voltage, but the unit is easily brought up to standards by adding a grounded power chord, a fuse holder to protect against over current, a back cover to prevent exposure to dangerlous voltages, and maybe even add an AC ammeter to measure the current consumption of the equipment connected to it - that will pay off in many ways! Ths unit was made with a vintage US made Genral Electric variac. Also perfect for lighting brighness regulation without the noise that dimmers generate!
Features: AC plug that plugs into any 117V AC household plug. Provides a socket in which the equipment to be tested / revived plugs in. Has a knob that regulates the output voltage with a scale that shows aproximate output voltage: 1-11 - multiply by 10.
Lot: WARNING Only experienced electronics technicicas / electricians should purchase this item - or die - you have been warned! To use it as is, is dagerouns and it should be modified as described above before using it. PURCHASE AT YOUR OWN RISK! - One unit available - picture shows 2 perspectives to show all of the details.

16) Vintage US made Military Decade Resistance Box
Description: This thing was made in the USA during days when athomic bombs were considered serious wapons to win a war and thrown into the athmosphere - equipment made to probably outlast even the last human for a humanless eternety - rugged and tough!
Features: Set any possible resistance value know to man. the unit provides 9 switches: from x 0.1 to x 10 Meg Ohms with 10 positions for each switch each providing ten steps: form 0-10. Each switch states it's maximum current loading: form 4.5A (lowest value) to 2 mA max (highest value). There are connectors that accept banana plugs or if unscrewed, lugs to insert a wire.
Probably the toughest decade box ever made - it even has a rubber seal to keep water out.
Lot: 1 vintage resistance decade box as shown and described above (I only have one - buy no or it will be sold!)
