If we do not have the desired part in stock, we may opt to supply the manufacturer and vendor part number so you can order directly.

Model PS-7x High Voltage Power Supply

Electrolytic Capacitors

These are the filter capacitors mounted on the PCB. Each snap-in capacitor is soldered directly to the PCB. Note that older PS-7x versions use screw terminal type capacitors – either the entire PCB assembly can be replaced or the snap-in type capacitors can be fitted (by the user) using a careful soldering technique and solid extension wires.

Individual capacitors $15.00 each Order PN LL0217
Kit of 8 capacitors $65.00 Order PN LL0217-8
Kit of 9 capacitors $72.00 Order PN LL0217-9

Series Power Resistor

The 100 watt series resistor may fail as it is considered a “fuse” to protect the rectifiers in the event of a tube arc or other event.

Replacement resistor each Order PN LL0274

Model LA-x Communications Amplifier

Electron Tubes

The originally used Eimac brand 3CX/3CPX-800A7 tubes have become extremely pricey although still available upon request.

As a more budget priced alternative, we have now qualified and are use imported 3CX-800A7 tubes. These tubes satisfy most of the replacement requirements and perform well in the Lunar-Link products. The 3CX-800 version (NOT pulse/high voltage rated) are available and current pricing is issued upon request. Order PN 00009974

The imported 3CPX-800A7 (Pulse rated) tubes are available upon special order – estimated delivery time is 6>8 weeks ARO. Matched pairs are also available at a premium price. Current pricing is issued upon request. Order PN 00009960

Front Panel Lamps We can furnish either the traditional incandescent lamps or cool white LED lamps. The LED lamps do cost a lot more although they do last longer and provide softer (different) illumination of the meter scales. See the image to the right – the top RF deck has the incandescent lamps installed.

- Kit of 3 incandescent lamps $4.50 Order PN LL0160 Manufacturer PN: Sylvania #85 Description: T-1 3/4 Wedge Base, 28 V
- Kit of 3 LED lamps $24.00 Order PN 00009868 Manufacturer PN: EIKO LED-24-T1.75 Wedge Description: T-1 3/4 Wedge Base, 6>28 V Please note that the LED lamps are polarity sensitive – they should be installed and tested before closing up the RF deck lids.

Replacement Anode (Plate) Insulator Kit For models LA-12 & 22 (222 & 144 MHz). The kit includes the items near the red arrows; plastic sheet insulator, hold-down buttons (2 or 3 based on model), silicon insulating grease and, hold-down hardware.

Note: The image to the right shows a current production Model LA-22A. Your model (current or legacy)may differ in look and component type/count.

Cooling Blower Kit Various types of blowers have been supplied since the inception of the LA Series RF Deck product. We can offer replacements based on understanding just what to supply. So, we request that you send as much information as possible including images of the device and its name plate (both motor & squirrel cage housing) as well as any original purchase information you may have available.

Cooling Blower (blower only) As described above, various types of blowers have been supplied so send us as much information as you may have available. Manitou Systems can supply just the blower – with mechanical modifications to enable it to fit onto the RF deck. These modifications include adding a screw hole to the exhaust flange and removing the supply side restrictor. The customer is responsible for swapping and mounting the power cord & Cinch connector assembly to this new blower – a hole for the strain relief may also need to be added. See the unmodified & modified images to the right.
