Here is a virtually new centrifugal blower motor from EMB-PAPBST.  The motor was previously installed in an assembly that was damaged by water (the motor was never wet only the chassis of the unit it was in).  The unit was new so the only run-time the motor had was during product testing so probably somewhere in the 2 - 3 hour range. These blowers suck air axially in through the center of the blower wheel and discharge it centrifugally 360 degrees from the side.

vintage General Electric Thermocouple Heating Element, .75 amp, Form 7, Part 7499, Made in USA Not sure what this is used for exactly, but I suspect it came out of a vintage consumer appliance that was taken out of service. Best guess. The previous owner was an old time ham amateur radio operator who saved parts out of anything, if he believed the part was still good.

10.368 GHz PLL brick oscillator by Frequency West , model MS-760XOL (the higher power version). Contains a high-Q cavity oscillator at about 1725 MHz that is phase locked to the X16 harmonic of the internal reference ovenized crystal oscillator. Here, the XTAL is 107.8241 MHz, and the multiplier block is X6 giving output at 10351 MHz.

6 GHz PLL brick oscillator by Frequency West, model MS-540LMXO (the higher power version). Contains a high-Q cavity oscillator that is phase locked to a harmonic of the internal reference ovenized crystal oscillator. For the picture, I am using a 100.00000 MHz SC-cut crystal, which is not included in this auction.

6 GHz PLL brick oscillator by Fairchild Microwave, model MS-540XO--the higher power version. Contains an adjustable high-Q cavity oscillator that is phase locked to a harmonic of the internal reference crystal oscillator. For the pics, I have inserted a 101.33333 MHz XTAL, the X12 harmonic is 1216 MHz to which the cavity oscillator is phase locked ( X12 the crystal reference), and the multiplier block is X5 giving 6080 MHz output at the TNC female connector.
