New project Hallicrafters 818

[Red Raster]

It was me, I bought the hallicrafters 818 in Seattle.

You may have seen the ebay photo showing the tv intact, I know you would
like a closer look. No need to make another aquarium as a good crt sits on top waiting to be put back.
The owner said that she watched programs on this set up untill she was 5 years old.


Chasis is a little dusty and rusty. Missing the 5U4 was a bonus, Preventing
the owner doing damage by trying the set out before selling it.


Beyond the dust a ring test revealed a good flyback and of course
not having half of the wax tire sitting at the bottom of the hv cage is also a good thing.


Over all the bottom view looks promising.


I was impessed by methode of construction used for the rf tuner not only is it realy solid it's by far one of the easiest to work on.
With a good 16GP4, flyback and power transformer this set is on the way.
Well after postal strike is over and i get my capacitors from just radios.


Yes the blue tube tested good, Half a dozen good 6SN7s didn,t hurt either.

Handsome set, and that's an interesting turret tuner with the little printed-circuit traces.

Nice set!
In the shot of the underside, it looks like a small pink power resistor (towards the top) might be burned in two?

Congrats! That's a really cool set - I love the tuner.
I have a few of those Arturus tubes too. They were only a few bucks each on ebay back in 2005/6. I suspect they are worth a bit more now.

P.S. You take really nice photos

Just looking at that tuner gives you good feelings!

Of all the tuners i have worked on, I think this one takes the prize for beauty
and good engineering. While waiting for capacitors i decided to clean and lube
bushings and contacts.




The round contacts on the channel strips were easily pollished using a pencil eraser. Notice the copper plate used for adjusting the oscillator,This simple solid design sure beats tuning slugs in card board tubing.


Could there be a nicer tuner work on?


Drum assy, The shaft sleaved with brass bushings.

Also polished the stationary contacts and applied tuner lube.

Round 2 may be a little tougher


Supprisingly the broken wire wound resistor is still hanging by a thread and has continuity (R181 220 ohm 3 watt) couples the cathode of the horizontal output tube to ground. Careful scrutiny of the output circuit will done as both resistor and tube have been running a little hot.
TO BE CONTINUED.

Well documented and photographed.
