Hallicrafters T-506 scored

I got it working It turned out the replacement 6X5 wasn't making good contact. A little cleaning of the socket and tube pins took care of that.

Curling anyone ?






I've cleaned all the crud off the knobs. First, hot soapy water. Then, a toothbrush and Brasso. Next, I used a toothpick on stubborn areas. Finally, a little Novus #1. I wonder how long until the crud returns ?

6x5's have a bad reputation in the radio world for being prone to shorting out. Especially in those attractive Zenith consoles of the late 30's that used two of them, they would commonly take out the power transformer when they failed. Perhaps you just had a bad one.

I'd like to know what the rephased tag is in reference to as well. Perhaps it was made in '47 and sat on a shelf until the whole channel one mess was worked out, and then in '49 had the push button for ch. 1 hacked out and put up for sale.

Not to sidetrack from your post, I make a point of using the 6X5's that have the "X-Plate" style of design, like a 6X4 does.

But I'm sure that 25Vac filament voltage didn't help... I'm glad no damage occured as a result!!
