Teardown of a 1972 Sanyo G-2607 Portable Briefcase Stereo System - The Electronics Inside
Ғылым және технология
Most people can remember, or at least generally know, what a boom box is or was. However, what did the grandfather of the boom box look like? Was it a revolutionary product, or just a few bits bolted together in a box?
On The Electronics Inside, David takes us on a journey into the inner workings of a vintage Sanyo Portable Stereo Solid State Music Center from 1972! This portable music center was an all-in-one solution, featuring stereo speakers, a turntable, a stereo tuner, and a cassette deck. While it may seem a bit outdated by today's standards, David highlights the uniqueness and potential of such a device.

I have exactly same model, works perfect
Theses were quite popular in Australia at the time! Sadly most of the radios didn’t have FM here!
The record player is stereo. The two “wires” are actually shielded left and right.
Took a punt and acquired one of these at auction for my man shed. Everything appears to work except the record deck. When applying stylus to the record the whole thing just skims across. Unfortunately I don't have a manual and there doesn't appear any obvious adjustment on the back end of the arm. If you or anyone can help with this I'd be eternally grateful. The only reason I bought it was to play my old LP's. Thanks, Jeff
Bought my sister one of these for college in the early 70's. Sanyo but no mains input, batteries only! Surprised you didn’t spot the tuning CAPACITOR in the radio, to the best of my knowledge ALL radio tuners then used variable capacitors in the same sort of cable system. I took apart several radios of the period and they all had the same get up. Interesting teardown, Thank You.
I loved that Tech Moan episode also. Tech in a case instantly gets more interesting for some reason.
The variable item for tuning is a capacitor, the shield is to stop 50Hz hum pick up and I would guess the 2 cables from the pickup are thin coax's so it would be true stereo.
The turntable is a classic Idler wheel design. Very common back in the day, but kind of rare nowerdays. For the modern day, I would add an aux input and maybe Bluetooth. But I would prefer an aux input over Bluetooth if I could only have one of the two options.
Not long after Techmoan featured this I saw one smashed up and dumped behind a local litter bin. It was a bit too far gone for me to salvage. Also my grandparents had one of these with a 8 Track on it.

Wow - I'd loved to have seen one with an 8 track!
if someone did....well why not do it for a friday project? who would like to see that built? leave your like!
A contemporary version, yes, might work. Beach or picnic, what kind of speakers would you use to be both portable and "overcome" the sound of waves, seagulls, screaming kids ...? Battery, bluetooth, amplifier, radio, SSD, bit of messing about with the UI to make it approachable, fitting it into a Pelican case? No worries. I can't get my head past the speaker selection ....

All joking aside, the original concept of the 2 speakers on short leads means you could space them apart facing inwards. If you added another 2 speakers, you'd have a chance of blocking out external sounds (to a degree) without needing kilowatts of power and having your music heard 3 kilometers away?
Hello budy, how are you! I have the Sanyo G2614nk, I can't find the electronic diagram. Would this source be 24v?
I'd put in a good turntable cartridge, probably put a rechargeable battery pack in it, maybe upgrade the speakers

Mod the turntable to stereo too...
Play some music through the speakers from a modern sound source.

I'll have a dig about see if I have a suitable output / 3.5mm adapters that I can use.
I used to have 1972 National Geographic magazines from 1972 advertising these.
Q: What is the most unnecessary statement made online? A: "Correct me if I'm wrong!"
There is no reason to have these devices integrated with one another. There each fully analog modules with no micro processor.
He seems totally clueless. Waste of my time.
