My questions are 1. can I use this preamp with my LM3886 based amp 2. can I use the same 24 volt power i'm using for the main amp for the preamp?<br />Thanks in advanceAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-75281973289155826562014-10-04T12:05:55.714+01:002014-10-04T12:05:55.714+01:00I use 24 volts I use 24 volts DrStevensonhttps://www.blogger.com/profile/13901235832359203061noreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-12533983415949453492014-10-04T11:06:29.163+01:002014-10-04T11:06:29.163+01:00This preamp can work with 12V power supply or not....This preamp can work with 12V power supply or not. when i on the switch got sound and after 5 second not hearing anything. i must turn off and on back the switch got same prob...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-27546035325780302312014-09-28T21:46:31.974+01:002014-09-28T21:46:31.974+01:00thank you paul...... :)thank you paul...... :)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-9858031791416073342014-09-28T20:33:11.957+01:002014-09-28T20:33:11.957+01:00yes you can use a 4558
