I can't find a dial or tuning knob to changestations on the radio


This boombox has digital tuning. Look at the pushbuttons on top. You'll find a pair for volume up and down and another pair for tuning up and down.

Heater stuck on full heat


Did you ever find a solution to this problem? My 2001 Sierra does the same thing; if I turn on the heat to full hot it remains stuck for a while. Sometimes it sticks for a couple of minutes, other times it sticks for a couple of days. As long as I don't turn it fully to hot though, it doesn't stick. It has gotten worse recently.

Tube radio tuning thread slipping


The dial cord may will likely need replacement, good luck finding anyone who can do it. There are some chemicals ("non-slip" from GC) that might be applied to the cord at the dial or at the tuning capacitor, but I would recommend that this be done by a tech.

I have 1 1959 zenith stereo and the tuner needs repaired, i have it apart. and there is a broken string on the end of a small metal spring, how do i put it on the tuner. i can turn the tuner wheel by hand,...


1......Use new dial cord, old dial cord becomes brittle and glazed over the years.

2....the tuning knob shaft should have 2 or 3 turns of the dial cord wrapped around it.

3....the tuning knob shaft should be clean.

4...if there are any small pulleys that the dial cord rides on for smooth operation, they should be clean and free turning.

The biggest things ( as you might have guessed ) are that everything that has the dial cord running over it should be clean and free to turn if necessary.

The little spring is there to keep tension on the cord, otherwise it would loosen once it streches with age.

If you need dial cord, I believe Sony still has some. You may need to contact the Sony parts distributor for your country, but I firmly believe that it is still available.

Good luck......Rob

Tuner


This sounds major.....

The signal detection used in both radios and TV sets is via special voltage sensitive diodes which alter capacity as the voltage across the diode changes.
You actually change the voltage across the diodes as you move the tuning dial.

In your case the diode only sees one voltage and is locked to a certain station, because you are not altering the capacity to re-tune to another station...

So it appears that you have lost the ability to alter the DC voltage across the diode...

The design of the tuning knob may be where this fault lies, where the physical action of turning the tuning knob does not transfer the mechanical action to the item that changes the DC voltage to the diode....maybe you have systen that uses a long cord would around pulleys that gives you nice control over the tuning maybe its just a broken tuning cord...
Maybe the tuning is done by just a simple variable resistor I'm not familiar with this system but I have given you the bascics to start on...Unplug the cord from the AC wall socket then remove the top of the cabinet and have a look to see what moves when you turn the tuning knob it will soon become apparent if there is nothing moving when you turn the knob and thus lead you on to the problem....
Maybe the knob is just loose on its drive shaft...
