Title: Channel 1 sometimes doesn?t work after booting Post by: petereugenefoley on May 24, 2018, 11:03:48 PM So I had 2-3 voices that would sometimes disappear when you boot up the machine and traced it to the S3528 chips. I bought 9 replacements from Utsource and managed to get all the voices to work most of the time save for Chanel 1. I went through like 5 S3528s until I put in an old one from a previously nonworking channel and it seems to work. However, it will still sometimes boot without that channel. There is a signal present on the input of the chip even when the channel is dead.
The 4051s and buffer amps are all working as far as I can tell. Of course I checked the PSU and im getting all my voltages there. Thoughts? |
