[Drakelist] T-4XC sudden loss of RF output?

Hello, I'm hoping someone could get me pointed in the right direction with regard to my T-4XC. I've been achieving 100W or above (depending on the band) from the radio consistently in the past. In fact, as recent as a day ago. This afternoon I was tuning up to operate on 80M and now I'm only getti

Re: [Drakelist] R4A preselector slippage

Joe - Sounds like wear in the vernier drive. The steel balls tend to wear a groove in the center shaft after 40 years or so. You may be able to get a repair kit from John Kriner, I don't know if he still has them. 'The Man's Amateur Parts Supply' or 'tr7dude' on eBay. Another list member

[Drakelist] L-4B Power Switch

Question for the group: to address the power surge issue and the vulnerable power switch issue, I bought an Ameritron ARB-704 rated 240v. Until it arrived I didn't know it is also rated 10A. The L-4B takes 15. Any way to bulk up the unit to 15A? Sent from my Verizon Wireless BlackBerry

Fellows I have a question about the preselector on my R4A: The red pointer doesn't want to move past the 15 mark on the dial face. If I apply some light upward pressure to the bar connected to the three tuning slugs the dial will pointer will move up to the 10 mark and pull the slugs further out of

The dimple in mine is quite worn and unattractive so I'm looking to replace it. Any help would be greatly appreciated. 5-NB blanker and preselector dial decals have been found but I'm still in the market for an SCC-4 calibrator. I understand that there's some "universal" ones out there, but I p
