Solid state vintage….
I’m a sucker, I found a 1978 Roland GA-120 on craigslist, DOA. $40 and I was hauling it out of a store room in the Newport Music hall (sold by the house sound guy). This is a solid state amp that was the predecessor to the Roland JC-120. I ordered a service manual from stereomanuals.com. I tore it down when I got home at cleaned it up a bit. It’s now sitting in my office waiting for some troubleshooting. The first photo shows the cabinet with grill, chassis, and speakers pulled.
Pre Cleaning detail
Tolex is a vinyl product and pledge applied with a toothbrush worked wonders.
The only publicly available reference I found was the users manual in Japanese.
Post tolex cleaning, I think I’ll hit the ply wood with some spray paint before it’s back together.
