Akai EWI3020m Disassembly & PCB Pictures

Image
The EWI3020m's "non-volatile" memory battery is soldered directly to the main PCB, which means you have to take the whole PCB out in order to desolder and replace it. I took my newly acquired EWI3020m apart a few days ago to replace the hardwired battery with a coin-cell battery holder. Every one of the boards are single-sided Phenolic Paper PCBs populated solely with through-hole components and even jumper wires. You can see in the pictures that even some of the ICs (the CEM3374 VCO and EPROM for example) are socketed! Certainly makes repairs a happier experience. Here are a few pictures of the disassembly and the main PCB itself; apologies for not having a suitable scanner!

Have had it for a few years, and it's always worked perfectly well - just took it apart for a second time to check more carefully for any obviously bulgy caps. It seems that these monitors (or at least their picture tubes) were manufactured in Ichinomiya in Aichi Prefecture, Japan . Apparently mine was manufactured in 1996. Mine had a few defects when I got it (missing Sony logo, kind of grubby, dumb calibration settings, base has been hacked apart for some reason - perhaps to fit into some rack mount?), but was overall a pretty good deal at $50, free delivery!

Not entirely sure what's the deal with the paper phenolic board though (FR4 was o
