Doing some reading and found there is a resistor that can totally take out the rx on a titan one. I have a diagram does anyone know which one it is..this is a 1 not. 2..I also just retubed it..so I know those are good.

Chris There are several key resistors that "if bad" (I.E. open) can take out the RX. There is also a crystal that can kill receive if bad. There are a bunch of things that can go bad and kill the receiver. There is no magic "Ah-HA!!" part that you can point to and 99% of the time is the culprit. It'll take a bit more troubleshooting than that to narrow down. |

Don't think I have seen a Titan one in 20 years.
Many radios will exhibit a single-point failure that happens a lot. Maybe a designer calculated the wrong wattage rating for a resistor, maybe they bought a bad batch of that particular part.
There could be body of knowledge like this out there for the Titan 1, and if there is a "they all do that" resistor that goes bad I haven't heard about it. Doesn't mean there isn't.
This is the sort of discovery that comes from repairing hundreds, if not thousands of a particular model. Would be a cool body of experience to uncover if anyone chose to write it down.
And rumors on the internet might be correct.
Could win the lottery without buying a ticket, too.
Skepticism is your friend.
Just what is your objective?
Making a 50 year-old radio a daily driver will be a lot like restoring a 1968 car to take you to work every day. Lotsa things get replace because of age alone. Other things get replaced because of wear and tear.
The radio will nearly always be cheaper to do this than a car.
If what you're hoping is for a magic bullet that makes an old radio new again, think twice.
Please.
And if you're just doing casual research about a cool old radio, Sandbagger covered it from the technical end quite well above.
