Philco 41-290 (121) chassis restoration.



			This is a milestone day.	All the solid wire has been replaced.	There are wires tucked every where. The IF cans are next. They will be removed, resistors replaced......
....and the stranded wire are to be replaced. Then the cans reinstalled.	After the IF cans the remaining resistors and capacitors will be replaced.	This is one of three IF cans. See the internal resistor? It will be replaced....	...along with the lead wires.	2nd IF	New wires.
The electrodynamic (field and voice coil) speaker tested good. It was dusted and a small 1/2 split has been sealed.	Knock off some of the vintage dirt.		Replace bad lamp wires and used lamps.	More vintage dirt on the dial scale.	Reinstalled cleaned pushbutton array.
Next, add a power cord, add tubes and see if it works!	Well just can't add a power cord just yet. The power switch leads came off. The switch is made of "Unobtainium". So it needs repaired.	Getting the switch re-mounted was a chore. There was little room to insert long bolts.	But Good old American ingenuity is still around.	Got it! Now I can connect the power cord.	Installed into the chassis.
The speaker is part of the power supply. So it is connected for the first power up.	WE have life. I can pick up KDKA with out a tweak. That makes me feel good.	The internal antenna is behind the chassis. It is used for a good precision alignment. The lead wires are in good serviceable condition. The full alignment begins.	Underside with station presets (push buttons) installed.	This radio accommodates seven (7) pre-set AM broadcast band stations. I will get a set of stations from the owner. The 7 stations are to be distributed across the band. Each button can only accommodate a sub set of the whole band.	I have an extra bezel. I wanted to see how this looks with the rear illumination of the wine clear pushbuttons.
And the rear lamp lights when the band selector is set on Push Buttons. Looks Nice.	The push buttons are darkened when the AM band using the continuous knob is selected. And the right most BROADCAST indicator illuminates.	Police band (low Short wave) indicator works fine.	And OVER SEAS illuminates appropriately.		This is a new set of knobs, buttons and a bezel for this chassis. Wine buttons have been swapped in place of the solid brown.
I age this image with Amber tinted spray lacquer, front and black. I used VISIO, a cad program. But I have historically used Excel. Black background clear font. Set the height for .30" and width for .63". Trim as needed.		Open up the paper guides.	Cut out the station ID. This page has been sprayed with Amber colored lacquer front and back.	Looking good.
WGN being received in the shop tonight! All lights out in the shop.	All totaled this took me about 2 hours. I do not do this often so I am happy to oblige. I like a nice looking radio!		IMPORTANT! This is for shipping. There is an aliment slug under this cardboard. Remove before installing in to the cabinet. Do NOT twist the screw slug.
