Hallicrafters T-506 scored

[leadlike]

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.
