This is a timely question for me, too, since I'm considering making a modification to my Drake L-7, deriving cutoff bias from a resistor in the filament side, rather than the existing heat-producing

Fortunately, the biggest losers are those who have compromised their integrity. UNfortunately, they are usually the last to realize it; or to care. [on-topic relevance: closet kilowatts] Chuck, N4NM

Similarly, the Drake L-4B (and L-7) supplies use a 0.82 ohm fusible resistor in the HV line as a "glitch" resistor. When mine blew, it was a relatively benign event. A "Real Glitch Resistor" in seri

I wonder how long ago those RF Parts 3-500Zs were manufactured. RF Parts, on their website, acknowledges quality control issues that existed several years ago, but claims to have narrowed their sourc

That's too bad. My experience (1956, Detroit Institute of Tech.) was the opposite: My lab instructor was a ham. He knew I was, too; the day before the first lab session he said, "You need this lab li
