FW: [Kenwood] TS850 and SB200

[Pat]

Hello Mike, i own the TS850 and the relay is 12 Volts and you have a little switch on the rear side of thyeTS850 to commute, if you do that you will here it working when you transmit. Mine is workingwith the Ameritron AL-811 but you need to make a cable for the commutation.BE VERY CAREFULL with the voltage on tube amps !!!! If you have to work on it, disconnectthe amp from the power voltage a few days before you open it and than put a cable fromhigh voltage caps to ground and let this cable like that during all the time you work on it !!! 73 from Belgium                               Pat ON5SV> From: k9mi at sbcglobal.net> To: kenwood at mailman.qth.net> Subject: Re: [Kenwood] TS850 and SB200> Date: Tue, 18 Nov 2008 23:54:53 -0500> > I'm not an amp person, but isn't the relay on the 850 12 volts dc, and the > SB200 around 120 volts ac?
