Plans have changed - going with 3CX800A7 for now on 432. This is a parts
accumulation that never found bench time for assembly.
I have the following "AS-IS" excess to my needs - I will have the below at
Dayton and may offer a discount for deliveries at Dayton...
- Six (6) Acrodyne Channel 14 PA Boards. 28vdc/18amps per board. These
were shelved replacement boards for repairing dual-board 300 watt RF
Plug-Ins. Each board final section has (4) UTV200 80-watt dissipation
transistors. See http://www.microsemi.com/datasheets/UTV200.pdf for device
info (designed for 20 watts peak each Class A TV - Amateur ICAS at say
45-50% = 100-125 watts output per board). Boards are approximately 14"
square - should just need to add 1/4" aluminum heatspreader plate, heatsink
and power supply for up to 125 watts x 6 boards. Devices are available on
the web at $60 each. Photos and more info available. Asking $65 per board.
Discount for all 6 boards possible if sold together.
- Three (3) Acrodyne Channel 14 Splitter/Combiners. Will include with the
above for $10 each.
- Six (6) Acrodyne Channel 14 Quad Hybred Combiners (appears to be good to
500 watts or more) - these have 4 ports (two inputs, an output, and a dump
port for an external load). Now these are really pretty cast enclosure
assemblies! Would like $30 each (discount for all 6 possible).
I have photos of all and additional info that I gathered during my
collecting of these that I can email.
As I will have the above at Dayton, delivery can be made there or shipment
can be arranged after Dayton for a reasonable additional charge (I find USPS
Parcel Post to be most cost effective).
73, Bart W9JJ/1
