I think you "missed" those joints intentionally so that you could give a more-detailed overview of the system and other possible faults. It's more fun this way. Thanks.

I wish providing service manuals and making stuff repairable was still a trend. It's awesome to see that there even is a service manual and all that info it has, and for the product to be easy to work with.

Also surprised to see a service manual for a fairly modern consumer bit of gear. Impressive.

the black cover in the battery compartment was probably for a different model that had a built in clock, they usually had a spot for 2 AA batteries in there behind the d cells. they probably reused the rear casing.

I laughed, I cried, I was moved. It has become a part of me.

3D print some new knobs and you really have a winner. Well done Dave, that took me back to my techie days

This is a CLASSIC issue, power device mounted on a heat sink/expansion contraction. I have also seen this on an old high voltage TV transformer in a Pioneer large screen projection TV. Had to re-solder on several occasions but was the only failure ever on the TV itself! Great repair video.

Tech Tip: You'll need to 'sync up' the tuning mechanism before you re-install the front!

[GreenAppelPie]

I repaired consumer electronics right outta school like this, I gotta say it was quite enjoyable and generally speaking easy to troubleshoot and repair

[AdamSWL]

As a kid I remember excitedly pulling apart my Silver branded boombox which had 80W PMPO proudly emblazoned across the front only to find a couple of small paper coned full range drivers rated at 3w each. Put it back together and sulked for a while!

Hey Dave - How many attempts did you make to get the Radio Tuning Indicator aligned to match the Tuning Capacitor position? - Chris

[njdevfan]

You remind me of Steve Erwin. So much energy and passion for your work. Thank you for sharing.

[AndreasKoepkeAU]

That thing is a blast from the past. I used to work for a Tandy Electronics store in 1998-2000. I remember selling that exact model.

[coondogtheman]

Touching up cold solder joints has never failed me. I did it to an old 1980s ghetto blaster boombox the Magnavox D8443 because the audio power output was very low and cutting out and I touched up the solder joints on the main capacitor and a few dozen other joints and the radio works much better. I am in the process of restoring this set as best I can.

That eev blog multi meter is a must buy!

Thanks for the video, Dave! My wife and I really enjoy your colloquial turns of phrase. "Bob's your Uncle" is hysterical. I found this video because I just happened across a "Winner, Winner Chicken Dinner" pretty complete CFD-565 that's going to need new tape transport belts. I wanted to get one "portable/boombox thing" for travel purposes, should that need arise (it probably won't, but restoring this stuff is my retirement hobby) and I owned a "Fish" brand box back in the '80s. The CFD-565 was fairly inexpensive considering how "overbuilt" it appears to be. It lacks Cassette Bias/EQ settings, tape counter, and the like, but it seems to be much better built than some of these eye-poppingly hyperinflated boxes. My question (I'm in the U.S.) is why don't Sony boomboxes get more respect than they do? I think their specs are held to a more conservative standard than some of the "45wpc" cash register/calculator manufacturer machines out there, so I just don't get it. But then I wasn't really part of the youth culture that fetished the park it on your shoulder and turn it up phenomenon. I sold a bunch of them to those folks in the '80s, though. What am I missing? $3K for a no-name knockoff? Help me out a little...best regards!

You can resin cast a copy of the missing knob from the working one, if that sort of thing gets on your nerves.

Love your repair videos

Dave discovering the AC/DC switching made me chuckle.
We had a lesser model as radios in a casino I used to work at. They took a LOT of falls from six feet up. What usually did them in was too many face-down smacks to the volume pot or mode switch. Nearly every antenna got broken, but we used paper-clip chains Scotch-taped to the wall. They actually put out a decent quality of sound in small rooms, the Bass Boost actually worked.

[mohammedmreh]

Omg. This same model sits in my desk right now still working!

[HazeAnderson]

My experience level just increased substantially from watching this vid. Thank you!
