[ARC5] Annual *Real Bench Challenge*

[Christopher Bowne]

Here’s the pix of the adjacent bench.  It’s a combination operating and test/repair bench.  The light blue item on top of the T-195/R-392 is a Wandell und Goltermann AT-611 selective level meter, originally used for checking channel levels on frequency domain multiplex long distance cable and microwave networks. Essentially a quadruple conversion superhet receiver with continuous frequency coverage from 5 kHz to 18 MHz.  Has 400 and 1740 Hz IF filters, a product detector for LSB and USB, a 20 dB range analog dBm meter, and a very high
detent count multistep gain control to measure dBm levels from +26 to -120 dBm.  Makes a great general purpose sideband and CW receiver, if you can live with it’s total lack of an AGC system!  An inventory tag says this one was at one point used in the ATT Long Lines facility in Lake City, FL. The HT-32 and SX-101 Mk III are one the bench for repair to the 32’s final amp bias supply which is currently only putting out half its nominal normal -49 volts, causing the 6146 final tube plates to get white hot in standby.

The URM-25 is currently being used as an external BFO for my E. H. Scott SLRM which is partially visible in the upper right corner of the photo.  Since retiring back in August, I have done a major clean up, sorting, and reorganization of all my test gear, parts, and tools. Replaced old cardboard boxes with mostly the clear plastic shoeboxes all labeled as to contents.  The TEK 535A was a freebie, from Al, W1UX, turned out it came from the University of RI EE labs, I may have in fact used it there when I was at URI majoring in EE in the early 70s.

>> Go right now and take a photo of your work bench without moving or cleaning anything and post it.  You can post up to about a 135k .jpg direct to the list or use a host like Google Photos.  You're on you honuor to post your bench as-is this moment.   No excuses if you think it's messy:  it's ok we're your friends- we don't need them.  Should make for interesting conversation.  Here's mine:
