Restoration is an Addiction
Sooooo.....my next project is a really odd duck, the Marantz SR9000G. Very little information available on this unit but appears it might have only been sold in Germany in 1979 or 1981 depending on the information source. Definitely confirmed it has a variable voltage switch on the back so might support the claim of an international unit. Apparently puts out 130WPC so that definitely attracted me to it but I understand the 1980's styling isn't for everyone.
It's a little beat up with dings in the wood case and missing the grill which I figure I'll never find as it's an odd size. Will wait to decide on refurbishing the fake wood case until I listen to the finished project. Should be worth it but don't want to invest the time/effort/money until I know for sure.
Test on DBT and no shorts. Connected my test speakers and the unit works but is very scratchy with volume and balance adjustments. No surprise given the dirty condition inside and out. Starting with a good cleaning and then mapping out the boards for cap replacements along with a few resistors. This unit actually uses some fairly modern transistors so none of the old SC458's or similar to replace.
Here are a few before pictures of the outside. I'll document the boards as I move forward.
