Hi!
My make up gain circuit for my NYD EQ is more or less finnished but still something quirkie about the sound. hard to explain, like it has somekind of harshness/messyness but on scope it looks quite good and thd is very low on my computer when doing a round with sinewaves.
the OT is 9+9 : 1+1+1+1 and i have connected half of the sec as feedback to the first cathode like in the pultec.
yesterday i experimented with hooking the centertaps of the sec windings together with 4.7k resistor (without resistor it would osc like crazy) and even grounded the output ct.
this seemd to make the sound more open, breathy and sweet.
i cant fig out whats happening and how/if i should persue something here.
the OT feeds my DAC. i thought maybe the OT wants to see a transformer balanced load and felt better with a ground referenced CT for the job..?
sorry for the uncertainty but i cant get a good thought out of this yet.
any ideas??
