Pacific have been out of Kenwood for ages,
Best bet is to contact Kenwood directly, or try RF Parts.com in the states.
Before you do that, check if the power module has in fact "Spat the dummy" as
many of the TKR-720 and 820's suffered from dry joints in the PA stage. So
firstly I would suck up, clean the contacts and reflow with high silver content
solder, especially around the inductors.
Check for high (Or normal) current draw when running the repeater on 12
volts and if there is little or no RF out the transmit socket, suspect dry
joints. I've re-soldered more TKR final stages than actually replacing the
Hybrid PA module.
Hope this helps?

there is a company here in New Zealand that used to or maybe still does deal
with Kenwood products

Hi
Does anyone know of a good source for a M57729h-01-p.
It is the UHF power module in the Kenwood TKR-820.
It is rated at 30 Watts 12 volts 440 to 470 MHz.
I found that they do not like to be operated into the wrong side of a
duplexer. For even a short time.
Is it used in any other transceivers that might be purchased for the module?
Thanks
