Put them right across the 50 Ohm input. Break-down was 95 volts. If you need Receive protection, Maybe back to back 1n5711’s Conduction at ~0.25 volts………. WA6VAB

OK for vacuum tube equipment, but too high for semi-conductors. 73, Don W3FPR On 6/29/2021 2:16 PM, Ray wrote: > > In the Early days we used a NE-2 for front end Protection….. > > Ray WA6VAB K3 > > *From: *Frank Krozel <mailto:[email protected]> > *Sent: *Tuesday, June 29, 2021 9:33 AM > *To: *[email protected] <mailto:[email protected]> > *Cc: *Elecraft Reflector <mailto:[email protected]> > *Subject: *Re: [Elecraft] K2 / ESD / Diodes D16 7 D17 replaced > > Don as usual “Thank you” > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
