Hi Alan, I have a TX802 as well but I have never had it apart and havn't really got to grips with it at all yet,have only had it for 2 years, and it is easier...
Hi Jason Thanks for your suggestion, much appreciated. May I humbly suggest you give your TX802 a fighting chance. It wipes the floor with the TX81Z! Cheers ...
Y'know, I have two TX802s. Love 'em. Or at least love 'em enough to let them take 4U of rackspace ;-) But I don't really program with them all that much. I...
When I was talking about "performance sysex data" I was really just referring to patch dumps and loads. The V1.o firmware won't load Performances 33-64 is all....
I've used the EEPROM BIOS chips from discarded (very) old PC motherboards to upgrade the firmware of the Yamaha TX81Z. While it did work and it was very...
I sucessfully did updates to ALL my keyboards this way. For I own 2 eprom programmers this is easy for me to do. And in case of the TX-802 there's no need for...
I also had problems with v1.0, loading performance data I had from backup. It actually really sucked, because I had a bunch of performances specifically for...
Can anyone tell me the number of bytes in a RX15 sysex dump? I have been working on 4x and 8x memory expansions for the DX, TX, and now RX lines. I don't have...

Hi all, I'm a new member here, and was hoping to get some help. I have a TX81Z with a blown-up coil in the power supply (datasheet part L1.. Yamaha part ...
Hi, Welcome to the group! The coil (input hash choke) is part of the EMI/RFI filtering for the input power. If you had to you could do without it by bypassing...
Hi, Thanks for the info! What happened was- I was repairing a broken pcb on the power supply (board was cracked, traces got cut), right by the power...
If I recall correctly, the TX81Z has a linear power supply of fuse, switch, RF-supression coil, transformer, bridge rectifier, big cap, voltage regulator ICs...
Hi, everyone, I apologize for this rudimentary question, but I have just recently got my hands on an original "brown" dx7 and a tx802 sound modulator. I can...
