18. Replace DAC xxxx
with DAC xxxx
First removing the old parts - it's a hard to job to throw away a
working circuit.
The settle node placed in the copper house. Massive DAC ground.
DAC will come on sockets, allows to change the DAC and gives also a
change to test other types of DAC's.

First tests with
different types of OP amps
Today I used my 7904A with the blue P11 Phosphor - I like changing the
scopes often.
