Klystron OKI Electric 20V10 Flange UG-595, 15mm Ku band

From the looks of it, this was a tube that was used to parameterize the particular tube, not for production or anything - it has a Huges test report tab (number 038895 on it, and a '98 inventory tag, and older inventory tags going back to '73.  It is serial number 423.  It is in the original box, with original Styrofoam, but the top of the cardboard box is missing.

I've marked this as "used" because if there is a test report on it, it must have been powered up once - there is no other evidence of use, however, it is very pristine in appearance, no scratches on the flange, etc.

This is a 18-22 GHz 15 mm band Klystron which I believe puts it in the Ku band

there is an interesting article about using it here http://ftp.gb.nrao.edu/electronics/edir/edir114.pdf

 
BGY67A 200 MHz, 24 dB gain CATV reverse amplifiers 3 used $4 ea Removed from a CATV Head End system that was surplussed - system was supposedly working when shut down, but I have no way to test these devices, so they are AS IS, I've priced them accordingly.

The manual for these devices is located here: http://www.nxp.com/acrobat_download/datasheets/BGY67A_4.pdf

1.1 General description Hybrid high dynamic range amplifier module in a SOT115J package operating at a voltage supply of 24 V (DC).

1.2 Features

 Excellent linearity
 Extremely low noise
 Silicon nitride passivation
 Rugged construction
 TiPtAu metallized crystals ensure optimal reliability

1.3 Applications: Reverse amplifier in two-way CATV systems in the 5 MHz to 200 MHz frequency range

Table 1: Quick reference data

Symbol Parameter  Conditions Min  Max  Unit
Gp  power gain  f = 10 MHz  23.5 24.5 dB dB
Itot current consumption (DC) [1] The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V. 215 230 mA
Ortel Return Path Photodiode Receiver Module 2860B-E02 1 used $9 Removed from a Telecom/Video head end system that was supposedly working when shut down.  I have no way to test this device, so it is AS IS - I've set the price low accordingly.

The specification sheet is here http://www.emcore.com/assets/fiber/ds.2606B_PIN_Rx.pdf

Features
5MHz – 200 MHz frequency range
Flat response to + 0.5 dB
High optical responsivity
Ultra low optical return loss
75  impedance-matched

The 2606B CATV return-path photodiode module is a critical component for the delivery of high-performance interactive services for today’s twoway fiberoptic networks. These modules utilize PIN InGaAs photodiodes in robust 14-pin DIL packages that exhibit excellent sensitivity, low noise, and exceptional linearity in return-path optical links. The module incorporates a patented impedance-matching circuit, which optimizes very low noise gain in optical broadband receivers.

Eppley Laboratory, Newport RI, standard or Weston cell - one of the wires is broken, so while you may be able to fix it, I would consider this to be a display piece.  A standard cell is used as a voltage reference for calibration and measurement 

1 used 6.50 - you can read about it here:

http://en.wikipedia.org/wiki/Weston_cell  --- quoted below:

The Weston cell, invented by Edward Weston in 1893, is a wet-chemical cell that produces a highly stable voltage suitable as a laboratory standard for calibration of voltmeters. It was adopted as the International Standard for EMF in 1911.

Chemistry

The anode is an amalgam of cadmium with mercury, the cathode is of pure mercury, the electrolyte is a solution of cadmium sulphate and the depolarizer is a paste of mercurous sulphate.

As shown in the illustration, the cell is set up in an H-shaped glass vessel with the cadmium amalgam in one leg and the pure mercury in the other. Electrical connections to the cadmium amalgam and the mercury are made by platinum wires fused through the lower ends of the legs

 
Scientific Atlanta (CISCO) Status Monitoring Module 1 used $12 As pictured, Scientific Atlanta (now bought by Cisco) Status Monitoring Module, 539065.  On the front (pictured) it has a handheld controller port, on the back there is a coax connector, a 12 pin square male connector, and a db-25 male connector.  I have no way to test this, so it is strictly as is.  The stuff from this lot that I have been able to test has all tested good, but on this one, I'm clueless
I've saved this 5 inch CRT for decades so I could build an oscilloscope with it, or do something else fun - but I have a scope and I'm out of space, so this has to go - I can't remember whether I removed it from a piece of mil surplus equipment, or whether it came separate (in which case it would be unused) --- I don't see marks from where it would have been installed, so it very well might be new/unused/surplus NOS or whatever you want to call it.  I'm sure it's OK, I wouldn't  save a bad tube, but I have not powered it up and tested it (to do that, I'd have to build that scope, right? and then I'd need to keep the scope and I'd have an even worse space problem than I have now) - so this is AS IS.  It is time to  move this from my collection of really cool and interesting stuff to yours.  The tube is marked "made in Holland" so I presume the real maker is Phillips.

 

you can find a data sheet for this tube here:

http://www.shinjo.info/frank/sheets/011/d/D13-480GH.pdf Salient characteristics are:

2KV anode voltage
Green phosphor
6.3V 300 ma filament
Electrostatic deflection

I've sold the Mu-metal shield, so what is left is the tube only, I just haven't taken a new photo.

It is from their MPP series, read about that series here  They say: MPP cores possess many outstanding magnetic characteristics, such as high resistivity, low hysteresis and eddy current losses, excellent inductance stability after high DC magnetization or under high DC bias conditions and minimal inductance shift up to 2000 gauss under AC conditions. Applications include Flyback Transformers, Buck/Boost and Power Factor Correction (PFC), Inductors, In-Line Noise Filters, High Q Filters, and Resonant Circuits.
