muRata filter ID?




Hi,

In addition to some other mods, I'm considering changing some filters in my Yamaha T-85 to matched GDT types. I've read that it used two 280 kHz filters in Super Wide mode, and a third in Wide. I've located their position on the board, but I can't find the markings for what's in there now in any of the literature.

The three filters are all "A10.7D"; beneath that, after the "CM" trademark, there's a datecode of "J". The red dot is on the top left of the filter. Actually, it could be "A10.70", "A10.7O", or even "A10.7Q". I don't have strong enough magnification to be certain. Still, I haven't been able to find anything in the parts listings that start with "A10.7"

The final two filters (230 kHz) are "E10.7S". These have been easy to find.

Oh yeah, Yamaha introduced this tuner circa 1986. I think it is bone stock.

Any and all help greatly appreciated.

Thanks!

Jim
