[Drake] TR3 Help needed

[Garey Barrell]

Rick -

What brand of Final tubes do you have?  Are they all the same manufacturer?

The cathode resistors should be 15 ohm, 1W, and there should be one from 
each Final tube Pin 3 to a common point.

The White/Brown wire from the plate of V5 runs through a hole in the 
phenolic switch wafer just behind the front shield of the PA area.  It 
is there to couple the Crystal Calibrator signal into the front of the 
receiver.  It is NOT connected to any terminal on the switch, just 
dressed down along the front of the wafer.

This is a very low activity list.  You might want to check the 
DrakeRadio list on Yahoo, or the Drakelist on zerobeat.net.

> Hello Drake owners. Needing some help here with my TR3. I was trying to use 10 meters and found that things are not right. When i Bought the TR3 from another ham the radio was not working. The 12JB6 tubes where toast and i had to replace one of the resistors under the middle 12JB6 tubes. I think it was a 1 watt 27 ohm resistor. Anyway this other ham show me a wire the look like it came off of the band switch. the wire comes from a stand off by V5 12BA6 to the waffer band switch in the middle of the radio. Now i have seen a wire that they use in heathkits for tuning that just hangs in the air like that as well. Could this Brown and white wire be there for some kind of tuning or has it come off of the band switch? Rick VE7RiK
