R-390A CHECKED
We have come across a quantity of these famous Collins designed military receivers, from an early depot auction, these are NOT your typical “hamfest specials” or “blue stripers”. Covers 0.5 to 32 MHz AM-CW-MCW in 31 one MHz bands, read directly on mechanical counter. Has four Collins mechanical filters and one crystal filter, allowing .1-1-2-4-8-16 KHz selectable bandwidths, 100 kHz crystal calibrator, BFO, AGC, noise limiter, dial lock, two antenna connectors, twinax (balanced) and “C” (unbalanced). These are mechanically and electrically fully working, all mechanical filters good, tuned to military spec, may not meet spec for band runout (unit will be able to be zero adjusted for all 100 kHz segments in each band), units will otherwise pass the depot performance checklist. Physically they are as we received them, may be modified, may need cosmetic/cleaning work, may need repainting, may have replacement name tag, may have replacement meters. Various manufacturers (no choice), we send what is next available. Requires 115/230 VAC 60 Hz, 600 ohm audio output, 10.5x19x16.8, 92 lbs shipping. Used checked, $699.00. Please note: due to demand we can no longer accept preorders. When a unit becomes available, it will be posted on the website.

The RX MeterType 250-A is a wide frequency range Impedance Meter designed to permit accurate individual determination of the equivalent parallel resistance and parallel reactance of two-terminal networks and components. The instrument is completely self-contained and consists fundamentally of a refined Schering bridge circuit together with its associated oscillator detector amplifier null detector and power supply. Bridge balance is obtained by means of two calibrated dials which indicate respectively parallel resistance and parallel capacitance of the unknown. Uses Tubes 5718 5Y3 6AB4 6AG5 6H6 0D3. 20 x 10 x 12 inch 40 lb. (E1X) Used Reparable.

LS3-ROUGH
$39.00LS-3 Permanent Magnet Loudspeaker. This speaker is made by various manufacturers. Used with BC-189 BC-312 BC-314 BC-342 BC-652. The LS3 speaker can also be used with the BC-224 and BC-348. Mounted on the speaker is an 8000 ohm to voice coil matching transformer. We opened one and the transformer is: Pri: 8000 ohms Sec 3.2 ohms 270 – 3000 Hz 1 watt. Has a JK-33 input jack which mates with PL-68 plug. 6" diameter speaker mounted in a 8" x 8" x 4.8" housing. You will need to refinish these as they are very rusty. (E1Z) Used, 14 lbs sh.
