Default Partridge SE O/P transformers


I have been playing with a 300b Thorsten Legacy design using conventional power supply (CLC) with two different output transformers.

The first was a AudioNote AN144 cheepo trx which sounded quite nice and balanced, good in the highs and ok but a bit soft in the bass.

Then I bought some TK4519 potted o/p trx's - the issue I am currently having is that this trx seems to be bloated in the bass and grainy in the treble (been running for 3 weeks now at 8 hrs a day).

Has anyone else used the Partridge o/p trx? Did you get similar results or should I keep on running the unit in and hope for improvements?

I have tried different resistor types and capacitor types to balance the sound but end up with the same bloaty bass and grainy treble - I could of course be doing something wrong?

Any help or suggestions appreciated.
