Purpose of CF mod on Pre2?

[John Caswell]

Hi Eddie,
It is now becoming clearer, because the Pre2 has a fair amount of gain ergo the output level is high, I suspect that you are overloading the the first stage of the HD83. It will sound pretty awful.
As Bob said, and a lot of others, me included, the best way is to fed it from the tape output of the Pre.
I think that has sorted problem nr 1 so......... next
