I purchased two blue backlit LEDs with the intention of upgrading the TX7 I own, as well as buying a second TX7.
I'm realizing I'd rather get a multi-timbral TX802.
One I already put in the TX7 I own and am selling locally, I figure this would be a good spot to sell the other.
For a TX7 it is a simple swap. To place in a DX100 requires a bit of handiwork, as documented here:
The seller I bought them from was asking $28 each plus shipping, I'm looking to do an even $22 and I'll cover shipping.
