Harris MW-10 transmitter

I'm not totally familiar with the MW-10 (I almost engineered a station with an MW-50) but if they use the MW-1 as a driver for the final amplifier, the modulator should be solid state in the low level box. This is strictly a guess on my part since I've only had hands-on with the MW-1.
 
Thanks for the reply, Bill.

My situation is similar to your "almost engineered" phrase. I have been put on notice that I MIGHT be called in if the regular guy is unable to get this transmitter up and running at full power. I have lots of experience with the MW-1 and some experience with the MW-5 which uses a 4CX3000A as a modulator and a 3CX2500F3 in the PA. I'm not in direct communication with the station's engineer. I was contacted by a third party who told me that the MW-10 may need to be re-tubed and I'm a little suspicious of the tube numbers he gave me. As an example, I'm not even sure there is such a thing as a 4X15000. I suppose I'll find out for sure if and when I'm called in to service the transmitter.
 
Overkill, INDEED!

Just to be safe though, I'll install a water jacket around the tubes and circulate it to a cooling pond on the front lawn. ;D

Thanks for the info.
 
An MW-10 is just an MW 5 with bigger numbers on the meters. And it's subject to the same problems pretty much. Keep it real clean and real dry or it will BANG at you, the peak voltages in it can be fierce. Be sure all the factory mods are current in the thing. If you change the carrier tube, you'll need to neutralize it 'cos it's a triode. The pulse tube merely needs the static bias set to the book value and the 50% point of its duty cycle set. Past that. it's a pretty straightforward box.
