Hi All
So this thread will document my Wolverine build, this will be a winter project as I do not have much time to devote to to DIY things atm so it's likely to take some time. Time eaten up by work and domestic projects - new windows etc.
Anyway , the Wolverines is a DIY forums Class A/B amp which can deliver reasonable amounts of power on rails up to 70V.
DIY Audio thread below, for those interested
Wolverine Thread
I have done a lot of research on various related topics, PSUs etc and have come up with the following base spec for me.
Mono blocs so 2 of the following
PSU TX 2*42V @ 400VA gives about 60V for the rails so about 160 W into 8ohms, plenty enough for me.
Active rectification
44k uf caps per rail I have some Mundorf whoppers I sourced in a sale a while back
.
Soft start, I have some boards for this but am undecided as I have found some others that allow an unlatching on/off button to be used so will probably use these instead.
Speaker protection, maybe Neurochrome.
Need to source some cases, Modushop do some but will need to look at others , the main pcbs are quite long so this limits choice.
The BOM is quite long so I'll source this in stages as founds allow and there are choices on various parts I need to make , power semis etc before committing .
Anyhow some pcb pics to get the ball rolling.
