Philco 48-1000 restoration

[bandersen]

I've had this set on the back burner for a while now. Since several other collectors are working on theirs, I figure it's a good time so we can compare notes.

I had wanted one for years but had no luck until a local collector downsized back in 2020.
It in pretty good condition except for some damage to the right of the screen.
Someone sanded aggressively leaving a depression and no finish. Grr.




Here it is arriving at my place. Deceptively heavy set.


The chassis appears to be 100% original.


Although the Sams service info shows "bumble bee" type caps, mine is loaded with convention paper caps in cardboard tubes.


The CRT, yoke, focus coil and speaker are mounted to the cabinet. I supposed I'll have to unmount them in order to fire up the chassis on the workbench. I expect Philco service centers had test jigs.

I'll be using some CE Manufacturing twist-loc caps for the three man power supply electrolytics.


Curiously the first cap only has two symbols and values listed on the can even though it is clearly a four section cap?




It is C105 in this diagram. The other two section are used as cathode bypass caps in the sweep circuit.
Also, note C102 is in parallel with C103 in some models. I thought it was an old repair but no, it is factory.




Many, many caps to replace, but at least it is easy to unwrap the leads from the terminal strips.

I switch to working topside for a bit. The surfaces are coated with a waxy substance to is easily scraped off or dissolved with acetone. Nicotine/tar glaze? Condensed wax and from hot components?


The metal underneath is very clean for the most part.


I removed the three caps next to the power supply and cleaned. I'll be using two CE Manufacturing twist-loc caps.




The middle cap is a smaller diameter type mounted on a phenolic insulator.
I'll just hide a new cap inside the original cardboard sleeve.

Is that a Radio Flyer I see? :O

It sure is. Had it as a kid in the 70s, but not sure how old it is.

Here's that odd cap. Four sections wired up but only two marked on the can. Neither value is what the service info calls for.
