: Waiting their fate at the tech bench. Can you believe my wife let’s me have this much space! This room is 20 x 25

: You can see where I spend much of my life!

: Digital Scopes, HP precision pulse and waveform generator, Tektronix precision sine wave generator, B & K full solid state transistor analyzer and Heathkit regulated DC power supplies. Two digital multimeters, a Sencore FM signal generator for aligning those FM tuners and a digital frequency counter

: Used for certain components under test and repair, Pictured Tektronix type 503 scope, Sencore Waveform Analyzer and above it a Sencore “Z” meter digital capacitor and inductor Analyzer

: Housed in it a Monster powerline a/c line power conditioner and my reference McIntosh MR-71 FM stereo tuner used as a listening source on benched components during audio burn in

: Well for now until I get the picture correct. What you see is a Tektronix 4 channel digital scope 100 Mhz bandwidth. I use it daily. Just below is a Heathkit scope dual channel I have it connected to my Hickok 539C tube tester and to top it off a Sencore full feature digital capacitor analyzer (I also precision match coupling and audio caps)

: Tek sine wave generator, HP precision pulse generator, Heathkit digital frequency meter, B&K vector scope and a multimeter

: Two digital multimeters, Sencore precision FM/MPX signal generator stereo load center, B&K Transistor analyist

: Upper unit “big meter” Sencore PR57, Lower unit the ever high current General Radio W10MT

: The famous Hickok 539C , but wait .. It’s highly modified and very accurate, I can precision match audio tubes and also tell how much noise they have

: More of the “extended” work space, wall of parts on the left

: My new “extended” work space

: Working late one night
