Re: Pilot PT650 "Spacemaker" Television
Hello Nick,
This is the contents of my 'Fireball' tuner box. You are most welcome to any bits you require. There is a screening cover and some retaining springs.
Note there are variations of tuners. Some have a large center hole on the coil disc and different valves are employed in some versions. The tuners themselves are probably U/S electrically.
If you get complete lack of signals on a Fireball tuner, check for HT volts on the anode of the mixer valve. [PCF80] If absent the fault will be due to failure of the tiny connecting wire from the IF output coil. It passes through a very short length of sleeving and chemical rot/green spot causes it to go O/C. It can be baffling when first encountered but easily repaired.
I can't believe that pile of scrap is capable of showing a picture again but I bet it does! Regards, John.
