Philco 20 Cathedral radio

Philco Model 20


I picked this Philco model 20 up in early March. It was found in a flea market in Greenbrier, Arkansas. As you can see there is some damage to the grill, but surprisingly all knobs were there.
An interesting thing you can see from above is the labeling on the  vacuum tubes. They say "Schmiers Radio and Refrigeration" and have a date code of 1931.



The above photos show you what the Chassis looks like removed. There was no rust, but there was thick dust covering everything. 

Progress on the Restore. 





As you can see I have replaced the old capacitors and have replaced the resistors with reproductions. The cabinet is coming along, but it will be fall before the temperature is low enough to lacquer and tone and the cabinet. 
One note from the above photos. The yellow caps you see are replacements for part 14. Which should have been a large metal cap similar to what you see attached to the back of the chassis.

Bell & Howell Oscilloscope Model 34 DeVry Tech

The Bell & Howell Oscilloscope Model 34 was purchased at an auction and then give to me. It was made by Heathkit for DeVry Tech (DeVry University). Below is a photo of the front after I finished electronically going through it. There was nothing interesting that came up while working on it. Below you can see some before and after of the underside. Below is the top side. The 2 filter cans were 4 sections of 20mfd for a total of eight 20mfd capacitors.  Below is the solution I came up with to replace them. It consists of eight 22 mfd on a PCB that is zipped tied to the bottom of the chassis.   Overall this is a simple oscilloscope and was a simple electronic restore.  Here is the schematic.

I picked up this radio at a local flea market. It was in fair shape and dirty. The radio smells like cigarette smoke as it heats up. Below you can see what the top side looks like. I changed all electrolytic and fil m capacitors. Below is the underside before I change capaitors. Here is a photo after:  The only issue this radio had was an open 33k ohm resistor coming off the meter adjust pot. The symptoms were the meter seeing a constant 7 volts across it and a lower screen voltage on the first IF amplifier. Once the resistor was replaced the voltage went away and the screen grid voltage went back to normal.  Cleaned up face.
