***Harbach Electronics Closed Until 26 April 2015***

16 April 2015:  Harbach Electronics will be closed from 16 April 2015 through 26 April 2015 as I will be traveling during this time.  Orders may still be placed from the website but no orders will be shipped until I return from my trip.  I will have access to email during the evening and will try to answer emails every evening.

***Pre-Dayton Hamvention SALE***

13 April 2015:  Harbach Electronics is having a pre-Dayton Hamvention sale on selected products.  The PM-300 Collins 30L-1 power supply kit is on sale for $60, the PM-800 Amp Supply LK series power supply kit is on sale for $80 and the PM-2500 Dentron MLA-2500 rebuild kit is on sale for $85.  All prices are plus shipping.

***PM-2500 Upgrade Kit for the MLA-2500 & MLA-2500B In Stock & Shipping***

11 March 2015:  The long-awaited P-2500 upgrade kit for the Dentron MLA-2500 & MLA-2500B amplifiers is now in stock and available for shipping!  All back orders for the kit have been shipped as of today.  Due to the length of the instructions for the kit (16 pages), instruction sheets will be sent to customers as a PDF file via email.  The instructions for the kit are also available in the downloads section.


***RY-L4B Back In Stock – Temporarily***

05 March 2015:  The RY-L4B is back in stock temporarily!  I have been able to find 30 of these relays at an affordable price.  Once these 30 are gone, I will be out of stock again until I can find another supplier with a suitable supply at a decent price.

***NEW PRODUCT – ES4SB220 SB-220 & SB-221 Filter Capacitor Block***

26 February 2015:  Harbach Electronics is proud to announce a new product in our partnership with Electronic Specialties, the new ES4SB220 filter capacitor block.  This product is for those wish to add additional capacitance and filtering to the SB-220, SB-221 & HL-2200 beyond what is provided by the Harbach Electronics FB-220 kit.  This is achieved by using high quality 330µF 450VDC snap-mount electrolytic capacitors to provide excellent filtering at a significantly lower cost than using the physically larger, more expensive screw-mount computer-grade capacitors.  The standard FB-220 filter capacitor block is also still available for those who prefer the computer-grade electrolytic capacitors.  The new ES4SB220 kit is in stock and available for shipping.  The instructions for the kit are available in the downloads section.


***NEW PRODUCT – Multi-Key in Final Beta Testing***

21 January 2015:  Harbach Electronics is proud to announce the new Multi-Key!  This is a multi-function external amplifier keying interface that can interface ANY amplifier with ANY radio.  The unit features 2 PLA-140 solid-state relay outputs and a DPDT isolated relay output (phono jack and 3-position terminal strip).  The unit also features complete isolation of the transceiver from the amplifier to protect sensitive keying circuits in modern transceivers.  The keying circuitry is based on the W8ZR StationPro and was developed in conjunction with W8ZR and WA2QBC.  Kits should be available in about a month after final beta testing is completed and enclosure panels have been milled and silk screened.  There will be a Multi-Key information page added to the website soon.

***PM-200, PW-200, PM-300 & PM-CLIPL Kits Updated With 220µF Capacitors***

06 January 2015:  In response to customer requests, as of 06 January 2015, the PM-200, PW-200, PM-300 & PM-CLIPL kits will now be supplied with 220µF 450 VDC electrolytic capacitors instead of 180µF 450 VDC capacitors.  Prices will not increase with this change!

***New Product Announcement***

05 September 2014:  Harbach Electronics now carries the ON/OFF & CW/SSB rocker switch for the Kenwood TL-922 & TL-922A amplifiers.  These are NEW PRODUCTION original switches that are no longer available from East Coast Parts.  They can be ordered from the Kenwood TL-922/A section of the website.

***New BLACK Front Panels Available for W8ZR SP-II Station Controller***

10 August 2014:  A new black front panel is now available for the W8ZR SP-II Station Controller.  The panel is black with white lettering and includes a new power switch.  The panel and switch combo can be ordered from the W8ZR Station Controller page on the website.

***New Adapter Kit for the Drake 2-Pin VOX Connector***

03 May 2014:  I am now pleased to announce availability of the new RA-VOX2RCA adapter kit from Paul Kraemer, K0UYA.  The RA-VOX2RCA is an adapter kit to allow conversion of the Drake 2-pin relay connector used on AC-4 power supplies and L-4 series linear amplifiers to a standard RCA phono jack to facilitate interconnection with a traditional RCA patch cord.  The conversion also allows for easy connection of the AC-4 keying circuit to other linear amplifiers that use a standard RCA jack for connection of the keying line.  The kit comes with a new RCA jack, lock washer, ground lug and adapter plate.  They are available in the Drake products section.

***New Plug-In Relay Adapter Kits for the Drake TR-4 & T-4X/T-4XB***

19 April 2014:  In response to customer requests, I am now pleased to announce availability of 2 new kits, the RA-TR4 and  the RA-T4X/B.  These are plug-in relay adapter kits for the Drake TR-4 and T-4X/T-4XB radios.  These kits replace the old chassis-mounted T/R relay with a small PC board and new plug-in relay.  All components are included in the kits including a new relay, socket, PC board, wire, spaghetti tubing and complete installation instructions.
