Here's some great early Pioneer Boombox Information, check out the SK-80 with TV tuner, wholly cow I bet that one is super rare. I translated it to English, it says page 190 and there's a lot more but I haven't found any audio pages yet. https://translate.google.com/translate?sl=auto&tl=en&u=http://mtomisan.my.coocan.jp/page190.html
The Pioneer SK-70, this is a nice looking box, who wouldn't want one of these? https://yamaha1000.exblog.jp/11457873/
Yes, unique look! Like somebody back then installed the TV tuner into a box, pure DYI, nowdays it's been replaced with bluetooth and etc.
There was a short time in the late 70's when having a TV radio (without picture) was pretty big here and a lot of the Japanese Portables had TV audio but this set takes the prize for the really old school rotary dial. UHF and VHF, did they have both bands in Japan? They might have been working on the Marantz Modular Set Up where Marantz (Superscope) had a handful of boxes based on the CRS-4000 Chassis, add a few parts here and there for a variety of boxes. It would be nice to know if any member has one. Can one of the TV guys chime in on why it's better to have the big rotary dials and not string tuning that we normally see? I'm guessing the dials were left-overs after push-buttons came in.
I think the idea of TV Tuners in Stereos etc was to get better sound. Back then most TVs had Live Chassis so couldn't be connected to anything but an aerial. There is a famous family story about my Great Uncle trying to connect his TV to his expensive Radiogram to get better sound and blowing both units up. I once tidied up a colour TV from the mid 1980s for my sister and although it had an earphone socket the isolation was a small audio transformer feeding the earphone socket rather than a mains transformer at the input to the rest of the set. Most sets just didn't have any sockets apart from an isolated aerial socket. As for tuner types it very much depends on the number of stations. When (here in the UK) we only had three TV stations (all on UHF) four pushbutton tuners were common and perfectly adequate.
I guess it was a size issue with the dials, they only had that little panel on an existing box. My early VHS players had a strip of 13 buttons but they also had a rotary dial for each of those buttons under the panels so you could fine tune the main buttons.
Agree, this dial has more than 10 fixed positions - channels, 10+ separate buttons instead? Besides, they could have always borrowed this dial altogether from some old TV. I had the same one on an old B&W TV set -nostalgy..
This looks like it only has component tape decks but there's some cool information on it. http://showa-cassettedeck.cocolog-nifty.com/blog/2017/11/lo-d-d-99.html

I'm not sure if this one has been posted before https://blog.goo.ne.jp/domzoh/c/5cfb4d653d382dc153abdcf6794be907 I use the translate function in Chrome to read it. The writer describes his hobby as fixing Audio "Junk". That sounds like quite a few of us here.
Found anther one... https://www.hifiwalkman.com/walkman-随身听/索尼颜值担当sony-cfm-800-fm-am盒式磁带收录机/ check out this tiny Sony CFM
Welcome back radiorich! People come and go and with summer sometimes this is the last place to hang out. I really like that little Sony, I don't think they made it over here.
I found this Russian site where it lists boomboxes year by year using the translator it appears in Italian Richiamo Sharp (recallsharp.ru)
Hello Mr X , it is great to be back and Silver 965 that is very cool to see the Russian site ! I was working on my little Sony portable radio from the early 70s All the Electrolytic capacitors were shot they used no name cheapo ones . I use Nichicon for most of my needs and united chemical and Panasonic .
MR X, sounds good I will post some photos and every Electrolytic capacitor that I removed from the radio and tested were bad Sony used some really cheap capacitors in this set . I did one mistake and lifted a couple traces replacing one capacitor . It is funny how the world is so small after all there is a place I enjoy to eat they have a bakery and last summer they hired a new person well the new person moved from California and retired from working for Sony he was a Engineer at the repair and warranty center also that was one their major warehouses . really cool to talk shop with him About one my favorite brand and company Since I also sold and serviced Sony at my business and I had factory training on Sony products . Sincerely Richard
That's really nice, I meet someone every once in a while that worked for 3M with tape products, it's neat to hear the stories, one of the guys set up new lines for cassette tapes world-wide. I bet most of his neighbors roll their eyes but I find their work fascinating. It moved so fast and the tech just kept getting better.
