I got given one of these in 1988 when I was sixteen and I am still using it. It is amazing. Got Mission floor standing speakers now but there's something about the sound of this amp. It's so warm. I can feel most of the sound. Amazing.
hello I come from Poland and I have had a sonab r 4000-3 for 16 years I don't know what the differences were 1.2.3 but it's really great best regards and I have many speakers and amplifiers from that period but sonab is the king
I have a lovely high end Pioneer SA 9800 amplifier which needs repair at some point but I think it will be a mission looking at the design and construction of it.
That is what I like about this channel; there is always an eclectic mix of repairs and projects. Did you also repair computers from the 1980's, such as the Sinclair series of microcomputers?
@@chippieminton21 The Spectrum computer got a lot of people into computing. But it was not cheap computer when you started buying all the things that attached to it. I had several computers of the age of various makes, I gave them to a school after a comment "You mean to tell me computers looked and were as slow as that and took a week to load and after you finished loading it often failed?" Yes they did, more often than not! But I started with Atari, hard to beat graphics for the time. I spent ages typing out a programme fro one and showed my mote (who was Spectrum), he went out and bought two Atari computers. I almost finished building a Spectrum Computer into a metal box as I wanted to use it with radio (RITTY or Amtor can't remember now) as it put out a lot of interference. Never quite finished it, but it should be still in the shed, the only old one I kept. However, my first real computer was a Windows 3 or 3.1 Compaq computer. I think it had about 30 floppy disks to load the operating system onto it with. Wow, it was fast for the day, NOT. Thank goodness for Windows 95, made life a bit easier, sort of. Anyway, I digress, as usual :-l
@@BoB4jjjjs Yes I Started with a spectrum 48k, never had much to do with ataris but they did look competent. Then I got a spectrum 128k, the non amstrad version. Then Went to Commodore Amiga and that was a Platform I really liked. SInce then it's been the usual generic IBM pc's starting with a 486 66mhz, I bought mine of my then boss and it came with dos/win 3.1 preinstalled so I never had that pleasure lol
@@chippieminton21 Never had the Amiga, went to 64, had the Spectrum with the built in tape drive but if I remember Amstrad stuck their name on it. I stopped short of getting the big Spectrum, forgot the name of it now, but if you turned it upside down some of the keys would fall off lol. Remember the first modem 28k, WOW! Light speed!

I have never seen one of those Amplifiers before, of course it is a tuner amplifier. Be interesting to see the repairs as they progress. :-))

To richard good luck on servicng
The sonar r4000 hi fi amplifier
From paul chapman
Because of the type of case used leads me to the thought that it might be a Class A amplifier.

No, I didn't repair computers, but Mr Chippies full time job was repairing those 80's machines.
