Hi PSW, remember me? I'm the one with the dead yellow transformer on a Floyd Rose Sustainer. Well, I've found out quite a bit more, but could still use some help finding a replacement transformer. After months of sleuthing, a very nice guy on another forum took apart his Jackson PC-1 for me, and told me this was written on the transformer:
C9219-A
0543
Seems promising, but after a lot of googling, I couldn't find any info. So, I went and read all of the patents printed on the circuit board (4,907,483/ 5,123,324/ 5,200,569/ 5,233123), which yielded this:
Pretty interesting, eh? The mystery transformer is marked as T1. I went and looked at the circuit board, and c9 is 100nf, and r9 is 10k. The sustainer driver/pickup is 34 in the diagram (9.8 ohms in my guitar), and the bridge pickup is 24 (15.4k, also in my guitar). This at least showed me what was going on in the circuit, but I was still unclear, until I read this in patent 5,123,324:
Makes sense, and then there's this:
Ok, now I'm much closer, but I don't know where to find a transformer in this ratio range. I went through all of mouser, and couldn't find anything that fit the bill. Any suggestions?
There's a lot more about what the transformer does in patent 5,123,324, and a lot of interesting info about the harmonic mode in patent 4,907,483.
Any help you guys can give to aid me in finding a replacement transformer would be great!
