Can someone who owns this machine tell me what is the value of the inductor at L105? A clear picture of the inductor will also help.

I hope someone is willing to help.

I can make a photo when I get back home in 1 week. Can you indicate the location on the mainboard?

Thanx a lot. There is an inductor on the right hand side of the PCB marked as L105 to the left of the rest button, it is covered by that big 1000uf capacitor. That capacitor is next to the YM2413 chip. The color of the inductor green.

The item inside the red rectangle next to the reset button is the part I want.

Okay, is it not installed in AX370? (Just curious).

Yeah, unfortunately it is not and so the rest of the FM compnent circuit like YM2413. That’s what I am doing at the moment, I installed everything almost. I only miss the value of the inductor L105.

Very strange that Sanyo removed that while keeping the MSX2+ chip..... Maybe for a question of price?

Probably not a Sanyo decision but Sakhr. Sanyo was just the OEM in this case. They kept the V9958 so they did not have to design and produce a new mainboard, which would most likely be more costly.

If we look at the the content of the rom chip, we noticed that Sakhr didn't FM basic since they wanted to use the slots for other programs like Paint, Word Processor, Arabic Basic, etc.. Also, it might be a reason to bring the price a little bit down for marketing matter regarding the middle east and the usual income that the individuals make at that area. But, it is just a guess.

The board of the Sanyo 70FD is a little it different than Sakhr AX-370 in some of the areas but not the FM circuit.

I will go on and try to guess that value of the inductor if I could not a clear picture of that PCB showing the area where the inductor L105 is.
