Stick with a big name tube. RCA, GE, Sylvania. After that comes
the big TV makers. There are garbage tubes out there like Lyndal,
IEC & a bunch of others. Maggy never made tubes as I remember.
They would get them from the big 3. Your biggest problem with
a 6JE6 is price. Most NOS gets bought up by hams for use in
HF amps.

220 is more than a tad too high. 210 should be maximum, preferably lower at the 'efficiency' coil dip point.

My 220 is pull the plug current, granted it should be lower.

Pulled the tube out today. You can see a couple cracks in the bottom of it. Magnavox Japan 6LQ6/6JE6C. Took a pic of the chassis tag but looks like part of it may be missing. Looks to be 5/68. I guess this is a 68 model. Here's some pics.

Nope--what you need is there. T 933-11BA Sams # 1005, folder1

Like others here have said...put in a good 6JE6 and damper tube AND horiz. osc tube--get in the dark (or/and put set on a variac) and see if HV comes up--WITHOUT and 'red plating".of HO tube. If you DO get ANY rerd-plating at ALL--power off till you get the sams and investigate.

Does anyone on here have a 6JE6 they'd sell before I go on evilbay? I'm seeing $25-30 prices.

It's going to be tough finding cheaper. Those tubes are sought out by ham's and CB'ers....The CB'ers are the ones that initially drove the price up in the 70's by using them in illegal homemade signal boosters (which were were badly designed and ate those tubes for breakfast).

[maxhifi]

If the horizontal oscillator wasn't working, it could easily red plate the output tube. Maybe check that tube too.

[DaveWM]

25-30 is on the low side of what you are likey to find. A good name brand NOS will be closer to 45-50$ just the way it is. This is why I recommend you get the cathode setup to monitor current, Red plating even for a short time can ruin it.
