L3 linestage as poweramp?

82.134.81.178

Since I have speakers with 108 db sensitivity I am thinking about converting the L3 linestage to a poweramp. Is this doable with just changing the OPT's to for instance a couple of good 5k/ohm OPT's?

Since the circuit consist of 2 5687 stages it har alot of gain, and is therefore transformed down with the trans-027(028) 33:1 trannie.

Maybe a couple of other small adjustements have to be done?

This is just a small thought and would be interesting to test.

The reason for this is that I came across a schematic which is a
5687 - Direct Coupled - 5687 - (5k OPTs)and produces approx 1W power.

The psu consist of a 6x4 rectifier

BTW: I also have an old m2 (factory build-6sn7 linestage) but with the same psu as our L3 linestage (and older mains transformer).

Maybe I could test with this?

I have many thoughts in my head right now - and want to do some more diy'ing in the near future.

Sincerely
