RCA Radiodyne 28
#44

I checked and installed tubes, hooked up a speaker and made connections to the ARBE. A slow power up showed partial progress.  The A voltage shows 3 v. and there’s static in the speaker. Tapping the tubes produces a ringing sound that slowly fades (microphonics?).   
This is generally what I expect at first power up. I see about.1 amps at 110 v. Will continue to check continuity and run things down with the RADIOLA manual. Getting closer but no home run! - Rob
