- I see this has been talked about before but I have not found the information I need. I have an Amp Supply LK-500 that has bad load padding caps on 80 Meters. The factory caps were 470Pf 5 Kv N3300. I

- You might want to check eBay for some used broadcast micas that will handle this. They usually come in 500 pf values and will take the current without heating. Herb, KV4FZ ___________________________

- You don't need NP0 temp coefficient. A ceramic RF cap rated for the current and voltage is needed. The temp. coefficient can be N750 or even N3300 if the cap can handle the current and v. They are h

- Mark You can use CERA-MITE NPO, the max I was able to find was 170 PF, Its available at DIGIKEY, or parallel 62pf CERA-MITE - 564CC0GAA302EL620J - Capacitor, ceramic. 62pF 3,000V. $US 1.00 https://ww

- Rob You are right the current at 1.8 MHz is the issue. Check the current rate for doorknob capacitor, like HT50 page 11, blue line. http://www.highenergycorp.com/High%20Energy%20Corp.%20Ceramic%20Cap
