The Equine Assault and Battery begins again! Sigh.
First - I can't get to the Pearls.
Second - We wnet through the serious technical discussions, THEN lapsed
into one of OUR notorious wholly irreverent threads a little while back.
A bit of advice - Once you've used a ballast tube, DON'T remotely
contemplate moving the radio much at all! I firmly believe that the
iron filament takes on a brittle tendency. When I have ever moved one
after use, I ALWAYS remove it from the radio very carefully, and package
it separately.
The 47 ohm, or for that matter a 50 ohm, 5 or 10 watt resistor betweens
pins 2 and 7 works VERY well.
About three years running now, on 24/7 with no problems.
When you futz around with paper clips, you DON'T know what plating was
used. Better to use bare copper, or insulated copper wire with the ends
tinned with solder.
We've already gone down the path of kielbasa and OTHER ridiculous
possible substitutes.....<G>
Although I MUST admit this list has been VERY quiet of late.....
