Interesting to see that, even if it's way overpriced.  It has the same metal faceplate shape as my old ca. 1951 console but only has the AM band, and it appears to be black (mine has copper plating).  The changer matches the one in my 1956 Magnasonic.  It;s the old Magnavox mix-and-match practice.  I've seen older chairside units but nothing like that.

I regularly pass through an Amish area here in northern lower Michigan, usually after dark.  Most of the buggies are pretty well lighted.  But then, I'm sober, and it seems to be the drunks who collide with them.  What's interesting is that my first reaction is always "what on earth is that... it's something odd."  There are lights, but they are moving slowly.

Tube Consoles / Re: Magnavox Berkeley - CR198 chassis restoration

I agree, just need the $$$. My B+K 1801 freq counter has a working nixie tube display, but it does not read properly.

There maybe  a generational thing going on here.  I'm the child of Depression-era parents, and so I learned early on about making do and being thrifty (but also spending money on things that really are important).  If you always wait until you can afford just the right device, tool, or toy, you'll never have much fun.  So improvise and make do, and either you'll get the job done and have fun, or you'll learn what you really need to spend money on.

I did a lot of loaded bike touring (tent, sleeping bag, Svea cookstove, etc.) on a $110 ten-speed bike--not exactly top of the line.  And that was after I straightened the frame with a car jack following a collision with a car.  It wasn't a perfect setup by most standards, but I had lots of fun.  If I had waited until I could afford a fancy touring bike I would have missed the experiences.

The sleeping bag cost more than the bike did.  One very cold night at Stone Mt., GA in a crummy sleeping bag made me vow that the first thing I'd buy when I had money was a good sleeping bag.  And I did.  It's a fancy down one, highly rated at the time, and it has kept me warm and happy through many cold nights since 1971 or so. 

It's always good to have a list of things we'd like to have.  That gives some incentive to be frugal with unnecessary expenses so we can be free-spending on other things.  But meanwhile, do the best you can with what's available.

Motorola / Re: Motorola Stereophonic restoration at last

Last night I decided to pull out all five speakers to check physical condition and to test them and the crossover caps on my audio oscillator. The 12" woofer was pretty even (by ear) from about 36 Hz up to 500 Hz. The 8-inch midranges made noise from 400 to 6000 Hz and the 3.5" cone tweeters were clean from 5K until my ear's limit of 12K. I put them back in and wonder if maybe that 12" woofer should have its own air-suspension box built into the cabinet.  :-\

If you seal up the woofer, won't you change its resonance and mess up the overall balance designed into the system?  If it's easy to do it wouldn't hurt to try, but it's likely designed for infinite baffle/open box use.

I share your problem with the seasons--summer is when I fall behind on indoor projects.  I was out painting the spokes on the winter bicycle the other day.  Ever try painting bike spokes?  But this time of year, it's mostly outdoor recreation plus cutting the grass.

There are lots of sources for capacitors, but I tend to go to Mouser for electrolytics.  I bought a nice kit of film caps from Sal's Capacitor Corner:  Antique Electronic Supply sells some reproduction chassis-mount, multi-section can capacitors.  It will be interesting to see who others favor.

As in much of life, it's the jerks and fools who make things hard for the rest of us.  I commute to work on a bicycle year round.  I can do that because it's not very far, and because studded tires are legal for bikes in MI (nyaa, nyaa, car drivers!). I mostly comply with the laws.  Ride in the street.  Stop for lights and stop signs [OK, I'll roll through a stop sign from time to time]. Use arm turn signals [except that when I want to turn right, I point right--technically, I have to use the left arm, but that's so dumb on a bicycle]. Use lights.  Wear helmet. 

And now it's tourist season, and all the tourists are pedaling around, riding the wrong way, riding on sidewalks, riding without helmets.  Some of their maneuvers are so incredibly dumb that they enrage car drivers, and the rest of us pay the price.

OK, a dissenting view on "all the safety nonsense of real cars."  My Dad was a physician, a surgeon in the days before they had specialized ER docs, so he was the one who got called in a 3 a.m. to deal with people who hit trees or other cars at 90 m.p.h.--or even those who had accidents that were just accidents.  He saw first-hand what happened to the human body inside a metal and glass box.  He bought the "padded dash" option and had seat belts installed when they were not a standard feature.  He drove very cautiously.  One time he explained to me what happens when your head goes through a windshield.  In those pre-restraint days, the head often went part way through the windshield, which is safety glass with the plastic film sandwiched in.  After hour head is partway through, you sink back and the windshield hole closes up like a Chinese finger trap. The scalp ends up on the outside.

For some reason, we kids listened to this parental line of talk.  We may have ignored other good sense, but we wore our seatbelts all the time, every time.  (At least one of us continued to drive like a bat out of hell until gas prices spiked).

But please, no mocking of the auto safety movement, which has paid big benefits for all of us.

When I was a kid, you could fix a TV, but maybe not a cat.  Now we've got great veterinary medicine so we can fix cats surprisingly well, but TV sets are a mystery.  Actually, that's probably progress, because for most of us pets are really more valuable than TV sets.  I've still got my parents' first TV, a 1953 Zenith console, but I don't have the same kind of affection for it that I've had for various cats & dogs.

By the way, I've tried the soap, hair, and stink deer remedies.  Actually, the neighbors tried the stink remedy but the smell migrated.  The first two didn't deter hungry ungulates and the third option was a cure that was worse than the disease.  I'm waiting for a plague, or maybe an outbreak of poaching.  Anybody who wants venison, I'll send a map.

OK, nobody else has answered yet so I'll start.  On old electronics, the most common mode of failure s capacitors, and in particular, the electrolytic capacitors that serves a hum filters in the power supply.   That's a usual cause of loud hum. Replace them ASAP.  A short circuit could burn up the expensive and rare (maybe unobtanium) power transformer.  I'm assuming this is a tube unit.  Paper coupling capacitors can also fail with age, and if it happens in the power output section, the expensive & rare output transformers may go to meet their maker.  Capacitors are cheap; transformers are not.

The record changer will probably require careful disassembly, cleaning, and re-lubrication.

None of this is rocket science; it's just  a bit time consuming (order parts; wait for arrival; replace them one-by-one).  We are lucky to live in  a time when we have lots of information available online.  But I do miss the old local "radio parts" stores where you could drive down and buy the parts you needed.  Problem was, when we had them, I couldn't afford to buy things very often.

The deer managed to get their miserable snouts through a gap in two chicken wire panels and they gobbled up two buds on my poppy plant.  One blossom made it and the next two buds are farther in.  I wish it were legal to poison them, preferably some substance that caused agonizing deaths.  Aaargh.  My least favorite animals.   The rabbits are much easier to deal with, except when winter snows pile up and I forget to raise my fences.  But the deer....

That photo of the TV-only console looks just like my grandmother's RCA New Vista TV that I'm desperately trying to give away to a good home.  If anybody wants a classic RCA, call Chris.  Same cabinet (almost exactly), same control placement (except no tone controls), even same sort of grill cloth. 

Chris Campbell

What's up with the separate bass/treble controls--did the TV use a separate amplifier with its own controls?  And it's interesting that Zenith seems to have isolated the bass speaker from the record changer, something that not all bothered to do.  That meant feedback in some cases, or a need to limit LF response to avoid it.

Wow... Beat up, broken grill work, hacked wiring and the wrong record changer. 

About worth the opening bid IF you can pick it up.

I'm always a sucker for orphan devices, and sometimes the salvage price sets a good floor.  This one has the two big field coil speakers, maybe an added phono preamp, and the casework isn't beyond redemption (OK, that fretwork would require some effort, but in the short term you could remove it all).  Getting it for $25 wouldn't be a really bad deal.

What's that little round thing in the lower left corner of the left speaker?  I'm guessing maybe it's a photocell for an auto-brightness system?  I don't know much about Magnavox TV sets.
