FS is a very clean and 100% working 2m Larcan SSPA. It is rated for 24/7 key-down kW operation & runs on 50 VDC. Drive power is around 10W...._Note the #1 killer of these amps is over driving them so I suggest starting out at 2-3W input with the amp into a known/trusted meter and load and only then very slowly increase P(in) until a kW is achieved._ This amp was modified & tested before it was mailed by the master himself, Warren (VO1KS) and runs perfectly. However I have yet to fire it up here at my QTH. Warren let's them run all night long at full output power to ensure everything is perfect before it leaves his skilled hands. It is being sold as-is only because some people mistakenly over drive the SSPA and blow the finals. One nice thing about the Larkin over the Harris SSPA's is the finals are common and still available should you ever need one ! You need to add ample fans, T/R relay and connectors of your choice......$700 + shipping. SSPA will be double boxed (I do not skimp on packing). https://drive.google.com/open?id=16BMMAXuS3zmPk9m6iDQOMIJVKjGh3lnv Gedas, W8BYA Gallery at http://w8bya.com Light travels faster than sound.... This is why some people appear bright until you hear them speak.
