What I thought was going to be an easy 2 bakelite blocks, turned into a chore! On the other hand, I made a discovery that really helped the sensitivity, of the radio.
First, today's bakelite adventure.
Part 67, a single section .05uF block, has a hookup wire that terminates in an IF can. While disconnecting it from the block, I broke the wire, and it became too short! In order to replace that wire, the can was removed, but in order to remove the can, a grid cap needed removal too! I snipped it close, and it ended up too short for my liking, so it was also replaced. Fearing the worst, opening a coil, I was a nervous wreck, soldering on the coil lugs. I wasn't very happy with the clip leads on the can either! After that was done, an "easy" dual section .25uF block was next.
I only have 630V caps, so both wouldn't fit. No biggy, I just mounted one outside. I put the other inside, and while attaching the block, to the chassis, I thought, did I connect the one inside correctly? Not sure, I removed it. Yes indeed, it was installed on the wrong terminals!
After all of that, I plugged it in, and it worked!
Now for the good news. All this time, I've had the antenna set up wrong! What a difference with the correct terminals shorted and the lead on the correct lug! I had a random length antenna on lug 4 and terminals 1 and 2 shorted! When all else fails, read the directions!
Next weekend I'll get the remaining filter caps changed.
Enjoy your Sunday evening, and don't work too hard next week!
