Its all about the Music
Well guys, I while ago I decided I was missing these big receivers, they look cool, they sound great and they are very nice to work on, they have style, and there really is nothing quite like them.
After working on a SX1980, SX1010, SX950, SX850 and a couple of others, there is something about the engineering and design of the Sansui's which clicks with me more so than the likes of Pioneer, although I do a lot of them!!
But Sansui is my favourite for repairing and servicing.
So, I started putting the feelers out, I really wanted to grab a G9000, but not at the current auction prices, they are fetching big money these days, I needed a fixer-upper....
Well, one came my way!! With the generous offer of an AK member we struck a deal (I can't thank you enough Toby), and pretty soon it was on its way to New Zealand...
It arrived about 3 days ago, and presently I am very busy with work and my race car with a blown engine, so I put the 9000 aside for a "rainy day".
But this afternoon whilst I came to a standstill with other work, I got the 9000 on the bench and got to work!!
I had to do dial lamps. Some holders were missing and the wires cut, the ones that had lamps were the wrong lamps, was a bit of a mess but not problem I had enough spare parts and warm white LED's to make it all work.
Replace some blown and missing output transistors.
Replace blown Soft start resistor with the correct wattage and value.
Clean and clean and clean and clean and clean some more, she was a grubby little Sansui....but as always scrubbed up well.
I replaced some corroded caps on the regulated power supply board. That glue had got to them, I checked all the voltage dropping resistors and made sure everything was in spec.
Fader-lubed the trimmers on the driver boards.
Fader-lubed controls and deoxit the switches.
Reconnected a broken connection from the filter board which was stopping the Right channel working.
Set Bias.
Set DC offset which incidentally is very stable.
Ran it up and had a listen.
Its going to get the full KevZep resto in the near future, but I'll have it in service in my music room for a while before I do that...
There is another surprise on the horizon which involves me selling some of my 2nd McIntosh system...You will all be the first to know!!
A sight to behold, the G9000 on the bench!! I love working on these things!!
Then the McIntosh MC2205 and C33 was cast aside to make room for the big G!!
