Wanted to share the most recent restoration I just completed for a customer. One of the best Zenith Walton examples I have ever come across. All original condition with original factory stamped cabinet. Brand new capacitors/electrolytic's installed, out of tolerance resistors replaced, band alignment, tubes tested, shutter dial cleaned and lubricated, and new rubber chassis/cabinet washers for vibration isolation.

The eye tube is an original 6T5 Zenith engraved tube. Once I changed out the Meg OHM resistor in the eye tube socket she sprung to life. Sill has a lot of life left in it, strong! Customer wants the 6T5 left in the set. Very sensitive and an excellent 7 tube performer. The bass response is out of this world!

A video of the set in action: https://www.youtube.com/watch?v=-Sk6JMXOsos

Why wouldn't they want the eye tube left in the set?

Excellent work, Jon! Beautiful radio! Job very well done!

Hcompton, the customer may not want the 6T5 left in the set because it's a rare and expensive tube (like $200 expensive). Most collectors keep a 6T5 to show off the radio at competitions and the like, but run a 6E5 in the radio when it's just at-home daily use.

Alright, I'll bite. I'm not that familiar with sets that use eye tubes or the tubes themselves but I know what they do. What's the difference between a 6T5 and a 6E5, to me the specs on radiomuseum look the same.

The 6T5 is electrically similar to the 6G5/6U5, but the pattern of the 'eye' is entirely different. In fact, as shown here, it's unlike any other eye tube, AFAIK, sporting a 'bulls-eye' pattern with no center post. Zenith (and maybe a few other manufacturers?) used it in 1938 as an attempt to get around RCA's magic eye patents, but gave up and switched to the 6U5 the very next year.

6T5s weren't made for too long after that, and are consequently very hard-to-find today. Given that 1938 Zeniths are highly sought-after by collectors, the few NOS 6T5s left tend to go for big bucks, and even used ones can command a fair amount. My own 9-S-262 has had a 6U5 or somesuch installed at some point, and it will likely stay that way unless I get extremely lucky and find a 6T5 cheap.

Oh yeah, you're right, 6G5. My bad. :oops:

They were made overseas, too. Bricor made a 6T5, I have one.

You can see the patterns of various eye tubes here:

Interesting. Are you sure that Bricor actually made the tube? According to this article, the only companies who actually made 6T5s were Sylvania (Zenith's tube supplier) and Raytheon. Anyway, my favorite page for pictures of eye tubes, as well as their patterns, is here: http://www.sm5cbw.se/tubes/eyes.htm

Too bad about the bezel. They can be repainted.

A beautiful restoration job on that radio :D Did I notice that this one has the extra light above the tone control?

One suggestion about the eye tube if I may. On all of my radios, I have installed a mini toggle switch for one of the filament lines in a location that does not stick out like a sore thumb. This way my eyes are off till I want to show them off. Don't need them to tune a radio any way.
I know the purists are giving me the stink eye right now because it modifies the radio. I totally get and respect that, and this is a Walton. This is a suggestion and your choice only and is a moot point if you rarely play the radio.

Good work and keep em coming.

It looks nice. Did you try a three wire cord to provide a ground? Many of them work noticeably better with that ground. Grand Brass now has nice three wire, brown fabric covered cords with molded-on plugs.

Looks fantastic. Especially the bezel - you resisted the urge to pimp it up by over-polishing it. Thank you!! :D

Is the finish all original or did it require any rejuvenation?

It is "over polished". The inner lip should be a flat grey/black. The outer lip should show brass only on the high spots and then is should not be polished.

Actually there is a rather simple process for repainting these. There is also a durable metal-paint in a rattle can that is very close to the right shade and gloss (flat). But if it isn't broken why bother - - right?

The set still retains it's original good condition power cord per the customer's request. I did not know a three wire brown fabric covered cord existed, might have to try one down the road on another restoration. Thanks for the information.

Thank you. The finish is original and required no rejuvenation other than a layer of Johnsons paste wax I applied to the cabinet.
