That is a beautiful piece. Sanyo made the 2900k. People overlook Toshiba, Sanyo, Hitatchi for the sexy brands, but there are some seriously top notch offerings from those brands if you know what to look for when hunting.
Now that's a heavy duty design, no silly stk/sanken output modules in that!. And a screened toroildal mains transformer, not cheap in it's day. I've had to take the function switches apart and clean the plates and delicate sliders. Cleaning spray doesn't always do the job.
Very nice receiver, reminds me of my Pioneer SX-1250. Toshiba had a very good but much overlooked higher end audio line back then. Same with Mitsubishi, Sanyo, Hitachi and a few others. It’s great to find one in the wild that no one suspects of being worthy!
Speaking of the SA-7150, guess how I originally found your channel? From the video you posted years ago working on an SA-7150. I found it because I was buying one and was doing some research first. It turned out to be a fantastic music machine, these things are hidden gems of the "monster" receiver category.
With ozzy osbourne playing on one channel certainly justifies some maintenance ;) That's a nice peice of kit your neighbor's got there..best we start a petition so you can add it to your collection, huh? :)
And he got it for free. He is 3rd owner. I serviced this way back for previous owner. I laugh when i hear people spending hundreds or thousands for old receivers because so many are just given away. I have not paid a penny for the stuff I have and I will gladly take some phools money for it.
Thank you sir I like when you do the old high power amps and receivers. First one I watched was the akai unit you did with the blown stk modules. Sure wish parts would of been available.
Love, love, LOVE this receiver. What an absolute beauty and beast all rolled into one. Also, at 9:20-something- it won't sound a bit lower one side to me, only one speaker working on my laptop any more & you already know my ears are getting well-worn... Was just watching one of your older vids on a Toshiba Walky (The red one, smaller than the cassette it was supposed to play if it hadn't been killed by a sticky tar belt). That's two bits of Toshiba kit I'd love to see but likely never will lol
The little FM transmitter I use the right channel is slightly lower than the left also, the right speaker is about 6 feet from the camera and the left is 2 feet away.
Love your videos. I have a Yamaha CR-2020 that I have had from new. I live in the Greater Vancouver area. Can you recommend someone I could take it to, to check it over & do the 2 two service bulletins that came out years and years ago and do a recap as well. Thanks and keep up the good work.
Hey Dave Nice Old Receiver Is It You'r Friends Receiver? Oh It's You'r Neighbors Receiver. That's A NiceOne. I Think Most All Of Receivers Nowadays Still Have Dolby

Not necessarily. Dual mono is anything that has a seperate power supply. Even if they share the same iron it can have 2 secondaries. As long as they have seperate rectifiers and main filters caps they can be a dual mono design. A mono block amp has 2 senerate transformers and usually puts the amplifiers is completely seperate boxes. Some will use the same secondary but with 2 rectifiers and filters. These were called dual power supply. Akai made several integrated amps that were that design.
No, because the signal is not dolby encoded, I was expecting it t o be more like dolby b on a tape deck, that is rolled off highs, but it rolls off the bass.
Nice receiver! I have a similar problem with a portable stereo. When I switch from any other mode to the tuner I get what sounds like a scrambled digital sound before the radio plays. It's been doing this for years. Any idea what would cause this?

Good video, thanks!
I just fixed my sa-775 thanks to this video, same problem. You're the man 12v vids. These toshiba monsters sound amazing.
They do and the guy that owns it is deaf in one ear. Kind of a waste if you ask me.
Like an old friend this unit arrives for a friendly visit. In and our it goes.
Thanks for posting this! Haven't seen one of these come in from the wild for a LONG time. These were sweet sounding monsters.

Looking at that power supply and amp modules, it sure reminds me of Pioneer from the early 80's.......

I have the same unit with the matching turntable. Haven't even tried it yet. I'll have to get it out and work on it. I have too many projects.
Looks alot like the sx 1980 270 wpc very very nice.

Hi Dave. Do u have a Panasonic DMR-ES15 repair video? This model has a common problem with the Digital PCB and Drive.
I have a DMR es15. Has the digital board drive issue. Haven't fixed it yet. Have no idea what is wrong as of yet.
Now that's a posh tosh 😀
Hey Dave Nice Old Receiver

Still Have Dolby
It's the neighbors. I do lots of work for him.

Dual mono would have a separate transformer for each channel.

i had to replace a balance control in my Magnavox the element had a deep scratch in it
No new video for four days, where have you gone Dave?
I work 4 days on, 3 days off. I don't shoot any videos on my work days because after a 10 hour shift i am done for the day.
7:50 Giggles..😏
Are you surprised the sound changes when you push that Dolby FM button?
No, because the signal is not dolby encoded, I was expecting it t o be more like dolby b on a tape deck, that is rolled off highs, but it rolls off the bass.
Nice receiver! I have a similar problem with a portable stereo. When I switch from any other mode to the tuner I get what sounds like a scrambled digital sound before the radio plays. It's been doing this for years. Any idea what would cause this?
Probably dirty potentiometer like shown in the video. Work out the switches with contact cleaner.
Did you notice your title use to have an error, misprint.
?
Time for a full re-cap
Never going to happen. The guy that owns it won't spend money on it.
