The Electronics Lab

My electronics lab is located in the original basement of my home. The electronics workbench is located in the center of there room so I can access all of the other parts of the lab without going very far.

At one end of the bench is soldering equipment and overhead power, and at the opposite end of the bench is the 21AXP22 (ctc5/ctc4) color test jig and the scope cart. Years ago I acquired a RCA model CTC5 color set that was in very poor condidtion. It had a badly degraded faux woodgrain finish on masonite cabinet and the chassis was a disaster. I decided than rather waste a huge amount of time trying to restore this very poor condition set, that I would part out the chassis and use the good 21AXP22 and part of the cabinet to construct a 21AXP22 crt test jig. This saves me the hastle of needing the entire console with the picture tube next to the work bench.

I use a fairly common assortment of standard electronic test equipment for working on TV and radio chassis.  These are the pieces of test equipment that I use:

B&K model 415 sweep marker generator, B&K model 1077, Several digital volt/ohm meters, Variac, 20 amp Isolation transformer, and a RCA resistor/capacitor substitution box.

On the bench is a Gunfu desoldering station, a Weller soldering station, 140 watt and 250 watt, Weller soldering guns and the 21AXP22 homemade color CRT test jig for ctc5 and ctc4 chassis.

The scope cart contains a Tektronix model 475 dual trace scope, a Sencore LZ53 capacitance inductance tester, a Leader NTSC pattern generator, and a Funguung frequency counter

Behind the electronics bench is a long built in counter with my electronic tools chest containing the usual large assortment of small electronic tools, screwdrivers and nut drivers and my Hickock 633 tube tester.This workbench is used primarily for mechanical chassis work. Underneath the bench is cabinet and drawer storage for equipment and assorted electronic catalogs and books.

At far end of the room on the mechanical bench is a large small parts storage system. There are 3 resistor cabinets packed to the max with 1/2, 1, and 2 Watt carbon comp resistors (literally many 1000's). On the end of the bench is a 1950's vintage Uline parts storage complex that was acquired from a Tv repair shop in Chicago that was closing it's doors. The Uline system is filled with capacitors, switches, jacks, connectors, fuses, pilot lamps, many hundreds of pots of all descriptions, and assorted small parts hardware, and much more.

At the left end of the mechanical workmench is a shelving system for storage of parts that are arranged in small cardboard boxes and corregated parts bins. Included in this area are vacuum tubes(left), another Uline parts cabinet with NOS TV knobs from the 60's and newer, coils, relays, and cords. Below the Uline bins are flybacks, and computer parts. On the right most shelving unit is spares of various types, yolks, flybacks, tuners and circuit boards all salvaged from sets that were too far gone to restore.

On the opposite wall from the above photo is another single shelving unit with many 1000's of old TV knobs. Several hundred telescoping antenna rods, and various Western Electric (Genuine Ma Bell telephones) for use around my home and workshops. I have very poor cellular reception in my home and none at all in the bunker workshops, so my home and workshops are all hardwired for land line phones.

On the back wall next to the stair well to the Bunker, is another section of shelving with 2 Uline drawer cabinets. These cabinets contain NOS VCR parts, and Solid State components, along with several drawers full of un catagorized capacitors that I sift through when I cant find what I need in the rest of my parts hoard. This drawer unit also has a miriad of other stuff, shrink wrap, springs, alignment tools, tie wraps, amplifier tubes, antenna system parts, and several hundred NOS can condensers.
