Zenith alignemnt information isn't with each schematic in Rider. Need to find another model which includes alignment data. See if this one works?

:Does anyone know how to find alignment instructions for a Zenith 7S657R? I can't find them on riders or beitmans.

I just finished restoring a 7S682. I have alingment instructions for that. The two sets are indeed very similiar. Just a few different tubes on the power end. The only difference I notice right away is the 7S657R has an additional 'N' trimmer.
My capacitors should be here tomorrow. I haven't had any luck in finding some light bulb protection for the power transformer. I've been looking for a bulb with a socket that I can mount. It's been hard to find a bulb that has a 300 volt rating, let alone the mounting part. I dropped my fuse rating to 3/4 of an amp.
It will be nice to hear this thing purr like a kitten, and I know it's going to sooner or later. Especially with good help...Neal

Years ago they used #47 lamps in series with transformer high voltage leads. These bulbs are rated .15 amps. Much lower than your .75 amp fuse. 1/4 amp slo-blo fuses were popular in back and white TV's. Anything is better than nothing.

I'll get a 150ma to 250ma bulb soldered in there on the two end leads somehow before I fire it up. Good advice sometimes falls on deaf ears, but not this time. Right now I'm putting the electrolytics in. What about the voltage rating? I don't know what a #47 lamp is rated at. I wouldn't imagine that it has any leads or sockets with it? Should I just solder to the case and the end pin? Just wondering out loud...Neal
