Yes, depending on serial number of your amp it will output the correct level without any additional attenuation. New amps have the mod already done. I modified my amp s/n 423 by changing two surface mount chip resistors on the filter board in the amp. Not for the faint of heart. One of the chip resistors is the size of "16" in the date 2016 on a penny. TINY!!!
On older non-modified amps Pure Signal will only work at higher power since the level out the sample port is too low. It will work in the 1000 to 1500 watt range but not down to 20 watts like it does after the mod. Current production amps have this mod done along with several other mods that were incorporated after my amp was purchased. I HIGHLY recommend this mod be done by Elecraft unless you absolutely have the experience and equipment to do surface mount rework properly. Last thing you want is a $6000 paper weight I do not know when this mod was put into production amps. My Pure Signal has performed from 20 to 1500 watts output withy an Anan 7000dle (blue face) without any attenuation added. I have since sold the Anan but keeping the KPA1500 as it works VERY well. Solid and dependable after several mods were done to bring it up to current production standards. If you think I am kidding about the size of the chip resistor I can send a picture to anyone interested. I did take a picture next to a 2016 penny for reference 😊 -----Original Message----- From: [email protected] <[email protected]> On Behalf Of [email protected] Sent: Thursday, July 2, 2020 4:12 PM To: [email protected] Subject: [Elecraft] KPA-1500 Pure Signal Output Does anyone know if the RF coupler output in the KPA-1500 is functional yet?
