Emerson Model 698 Series B
 

This is a recent Craigslist find that I couldn't live without. Apparently it's a seldom seen model. I've found no reference in Riders. Sams website index refers to set 125 folder 6, which is for models 662-B and 663-B. However my chassis layout is slightly different. The model 662B is the more common Bakelite cabinet version. This cabinet looks nice enough that I'm only going to do a light touch up to it. I also plan on doing an electronic restoration to this set.

Both of the rear knobs are in poor condition. If anyone has an extra set I'll gratefully take them off your hands.

Neat find, Kevin! I've never seen that model before. What CRT is in it? Is that a 12LP4? I hope you find some knobs for it. Good luck.

Nice find :thmbsp: I'd only seen the bakelite version before. I just might have some of those knobs. Please remind me if you don't hear back in a week or so.

Very nice!

Thanks guys!

It uses a 14BP4, a rectangular all glass CRT.

Very similar to the Emerson we had when I was very young. Broken knobs and all. We used pliers to change channels.

Very nice set ! I am partial to Emerson tv's so I think its extra nice......

Can't wait to see a picture on it !

After years around vintage TV's I too have never seen that model. The stark, simple design is very unique. I'll always like vintage wooden TV's the best!
Enjoy it.

Very interesting. I have a 663, which much more closely resembles the 662--but has a 16" tube. Gotta love the oddballs! :)

Nice find Kev. Cute set!

Thanks for the comments guys. Last night I got the chassis clamped up on my work cart and started eying the situation over. First impressions are that there's tons of room to work under the chassis, and I like the fact that the electrolytic capacitors are all mounted under chassis, all 12 sections of them.

Unbelievably all 12 cap sections reformed to within spec for leakage current at their rated voltage. Most are below 1ma at 450 volts, not bad for original caps. While I don't condone playing these old sets with original caps, I do find it entertaining to see how they test and hold up under initial use. I'll probably leave these in for initial power up and replace them at a later time. I would never leave a set of this vintage with original caps powered up while unattended. :no:

There's a problem area under the high voltage cage that's going to be a bugger to recap. I think I'm going to end up drilling out the rivets on the horizontal linearity and size control bracket to get at the caps buried down in there. Also discovered the pink 750 ohm sand covered resistor is open, along with the fuse and a previously replaced 10K(green) wire wound resistor. That .02uf cap isn't suppose to be across the linearity coil either. Somebody was obviously having some horizontal issues.

Those coils just snap into holes in the bracket. Seems like it would be a lot easier to pinch the little topside tabs and slide them back.

You would think, but unfortunately the part that snaps in has been soldered to the back side of the mounting bracket. I thought it would be easier to pull the whole assembly than trying to unsolder while at the same time finagle them out of their mounting holes. :scratch2:

I looks like there was real problems with horizontal sweep. A bit of hack work, at it's best. I did the nut trick, when the adjustment slot got damaged, by using the wrong tool.
I'm trying to remember if other Emerson models used the air-core Flyback.

My father said he hated working on Emerson chassises, as they built the circuits in layers. That it was a PITA to access the parts underneath other parts.

This is my favorite hack repair so far - Looks like someone snapped off a section of a couplate to replace a 5000pf capacitor in the sync separator circuit. It has .003 penciled in the upper left hand corner. At least they put some corona dope on the edge for insulation. :scratch2:

The original owner of the set must've quit using the set, years ago. There's a lot of nasty capacitors that need replacing. It looks like a ratty junk was used for replacement parts, which you were referring to.
What EIA code is on the CRT? I don't think it's a RCA sourced tube.

EIA code 210, which I think is Hytron. The CRT tested very weak(like lower third of the bad scale), but I have a GE replacement here that should work fine.

I discovered last night that my flyback primary tap going to the HOT is open. I have a Thordarson Fly-2 ordered that supposedly subs. I also noticed that the vertical output primary resistance reads about double what's it's suppose too. Looks like this restoration should be a lot of fun before it's over. :)

While waiting on parts I decided to remove the CRT and do some basic above chassis clean up. Apparently this set was kept in a location that allowed condensation to form and drip off the CRT. It's the only place there is significant rust on the chassis.

I also found the break in my flybacks high voltage winding. It was hiding under a piece of insulation tubing going between the windings and the coil tap terminal. Unfortunately I found it after I'd already unwound a couple dozen turns off the HV donut. :o I was able to re-flow the wax around the HV donut, and everything is ohming out reasonably close. Only time will tell if I messed up my HV by removing those windings. Not sure if I can get away with running the HV winding wire directly to the solder cup. I suppose it could arc to something and vaporize that tiny wire.:scratch2:
