AB165 Bassman Upgrade

[caricbrown]

I have been working on updating a donated AB165 Bassman head. So far I have replaced all the caps and most of the resistors. I have also done some minor changes to remove some of the post CBS "improvements". The amp definately sounds better, but is no Dumble/Fuchs/Cornford.

I want to experiement with updating the amp further getting closer to an ODS 50 sound. What schematic should I start from?

Thanks.

Go over to the files section and check out Normster's bassman conversion. Should work for you.
