"The 2nd grid you mention for the 58's is the screen grid and usually operates at a voltage somewhat below the plate voltage. Traces to the 2nd tap (90 volts or so) on the voltage divider."

Values for 2 can electrolytics in tuner chassis of AW 12 Deluxe

I am working on my Scott AW 12 Deluxe.I need to identify the values of the electrolytic capacitors that are mounted on the tuner chassis. They are not marked with values but each one has a dot of green paint on its base when looking from the underside of the chassis. These are the tall can capacitors. One of them connects directly to the voltage divider resistor. In the circuit drawing this appears to be an 8 mfd and is the only one designated as electrolytic. The other capacitor connects to…See More

Hi Ken

Thanks for the note. Sorry for the late reply. I moved in October and haven't been on here until now. Regarding the Philharmonic speaker, I have done nothing to it so far. A collector I know swears by mineral oil on (dusted off) cones, but I have never used the stuff. Thanks for the kind words regarding the Philco book, I appreciate it.

At 12:24pm on January 15, 2014, Ron Ramirez said…

I would suggest gentle brushing of the cone with a small 100% Genuine Bristle paint brush.

Hi Ken. Thanks for the welcoming !  I've posted several photos of my Scott radio set and I hope someone can identify what exactly I have here... and hopefully a rough idea what it's worth

Thanks again

Rocco

My Philharmonic featured on SWLing Blog Post

Posted on April 6, 2016 at 1:14pm 5 Comments

I subscribe to an excellent blog called the SWLing Post. It is run by Thomas Witherspoon, a man who has boundless energy.

Recently he featured a Crosley radio that was competing for the high end market back in the late '30's. At the end of the article he asked if any of his readers had a 'benchmark' radio. 

I responded with a few photos of my BOL Philharmonic and he created a post from my information.

Replacing the 7 capacitors in the Bass Box

Posted on January 22, 2016 at 12:17pm 0 Comments

My Philharmonic had a number of problems when I first began to repair it. Once all the major problems were taken care of (thanks mostly due to several very helpful people on this forum) I finally got around to the nasty bits. There is rectangular box under the chassis which I think is called the Bass Boost Box. All seams are fully soldered together and the wires that leave it come out just one hole. It was recommended that I change out all of those capacitors. I saved that job for…

WTWW Christmas Photograph

Posted on December 29, 2015 at 8:52pm 8 Comments

The shortwave station WTWW runs a Christmas event each year. They ask listeners to submit a photograph of the radio you are using while listening to Christmas music on their station. 

Last year I submitted a photo of a Zenith Trans-Oceanic I was using.

This year I took a photo of the Scott Philharmonic which I recently put back together and placed in my radio room so I can use it. My photo is below. ( the knobs are all wrong - someday I will find a set).…
