[TenTec] Troubleshooting Argonaut 505 with low output

Hey Neil, when you say that you, "went to try your first CW contact.." does that mean you have made SSB contacts with the Argonaut?  In other words is the power output the same rather low number in both CW and SSB modes?  If SSB power is good, but low on CW I'd suggest exercising then cleaning the mode switch.  I can not tell you how many radios I've "repaired" just by working the mode and band switches, then some Deoxit carefully applied.  
The Argonaut is a fun radio, wish I had one again!   Wait there is a hamfest near me soon.......
