SB200 Linear Amplifier - New Fan & Motor Installation

In this video I install a new fan motor as well as a new fan blade in the SB200 linear amplifier.
WARNING: The voltages inside the amplifier are lethal and can kill you. It is imperative that you know how to work on “High Voltage” equipment safely before attempting any work. If you do not know how to safely work on “High Voltage” equipment, get assistance from someone who does before attempting any work.

I got the same replacement kits for mine. Just have to do the work now. I ran RG400 coax new inside and new BNC and SO 239 as well. I got ameritron external soft start both the 240V and 120v models so I don't need the internal soft start. looks great 73's

nice set up good job 73

[@TJCampie]

Ahh man I really wanted to hear if it was quieter than the original one. I ripped my og one out and put in some 12v fans but the circuit I'm using to power them is quite rudimentary so they bog on transmit, leaving the tubes basically uncooled until I unkey. Not the best practice probably.

Anyone know where a guy can find a replacement fan motor for this sb-200 these days?

[@alvarogaitan2529]

Mike terrific job 73 from kb2uew

Mike, when drilling a new hole in the chassis, how do you prevent metal shavings from contaminating the chassis?

[@edschaff6291]

mike, I want to make the SS-200 input networks accessable without dismatalog the amp everytime. would you make a small door or try to drill seperate holes each band with pop-in metal covers on each. Ed W6AOA

Hi Mike just wondering can you sell me a quarter wave ground radial hub that you make for the pl-259. Thanks

Mike, where can I get the replacement fan and motor in this video?

[@mefedler]

I purchased the one shown in the video from Harbach Electronics

[@dambuster6387]

I replaced mine with a much larger fan cut a hole to take a about 5 inch axial fan pushes hole lot more air.

Beware Chinese tubes are very poor quality.
