Some probably know- I probably knew at one time:
The bias setting for the osc. section of this tube should be 10 rather than 30 like the pentode section. The built-in chart for the 533/534 is wrong. The on-line doc. is correct. Don't throw away any good ones since it is the osc. for one of the Zenith TO models (one that does not use the 1L6).
