I have what I believe to be a Westinghouse model 801 columinair 8 grandfather clock radio and is looking for a good set of schematics.

I got that printed. Also found some info on pacific tv for just model 801 but the 801 looks to have more caps . Also here is chassis picture

Interresting the threaded shield cans. I found one on a home built equipment in some junk that I acquired. Wonder whats inside yours, mine had coils.

Mine is the two if transformers which will have coils.

Any help would be great has this looks to be a bit of mess. Here is a link.


http://pacifictv.ca/schematics/westingh ... manual.pdf


Page 14 shows all the cap blocks but do not match radio museum schematic has I will try to post
.

What's the number on that capacitor pak (Polymet?) underneath that yellow capacitor on the left hand side on your set .....C4621?....And how many pins or terminals of it?....The other one is a C4517 or 4517 nearby?

The polymet cap is c 4517 with 4 pins and the one in question has no number with 4 pins but one has been cut off and I assume it is the yellow cap. Sorry the c4517 has the wire cut not the other one.

Also inter stage transformer has 5 wires and one not connected and here are the 4 connections
- rf choke
- rf choke
- c 4517
- tone control
not sure of one not connected

Here's a page from a service lit limited as it may be but it does state there are minor differences in the the table set and the Columaire. (can't read it I'll send it to you)

https://app.box.com/s/ekz14ss8leihsjf2e3mfmvtddzut5yda
https://app.box.com/s/5t4dvpmbv0xofagh42eqrnd1r1qekm0v

In some models the 4423 (and maybe 4517) (according to above) would of been dropped in favor of a 4621 capacitor pak. Someone else posted on here that they had both paks present the 4517 and the 4621 which is probably the same as yours.. I'd probably follow the schematic on Pacific TV since the're minor differences as this guy did. You already know what's in 4517 and how it's wired...

They say they are similar to the R7 and R9 but you can see the're differences especially when it comes to the resistors.

Yep...seems the best you have...Unless there's some other factory manual for the Columaire-8 which is out there.(I can't find it) ...It's identical to the one in RCC and pretty detailed...Suppose you could always contact Dave at Just Radios for factory lit if he actually had it.

I might do that or see what comes up here first.

Any more info or help on this radio would be great. Also how does one replace the cap blocks? Do you just take out all together stuff or jus leave in place and add new ones.

I would restuff the capacitor boxes (there are 2)
Note that the filters (electrolytic) are separate.

The electrolytic are also in a metal can.

So--you can restuff that one also.....

Almost anything is fair game if you can keep the same overall configuration and wire routing. For example, it's not good practice to put any part in a totally different chassis location.

It is quite simple to restuff many of those cans, I normally line cans with insulation paper and as modern caps are smaller, that can make it easier. It can also mean that they can move around & short, so that has to be dealt with. The lining acts as a sleeve, should there be a need for future removal as well as restricting shorting to the can.

It is important to colour code the wires so that you can identify what is connected to what, especially when you get a can with more than eight in it. Silicone sealer makes a wonderful filler & binder but its insulation properties should never be relied on (not good).

There simply has to be a plan before touching anything.

Going to attempt electrolytic can first. Now to figure out the connection points.
