So this will be last nakamichi thread for at least a month.
I posted a bunch recently
So Taiwanese made Nakamichi ta-3a comes with regular transformer..not toroidal like Japanese made sr-4a
When it's on there is a faint transformer buzz if you put ear close to transformer. It's definitely louder than on other nakamichis I had
Ta-4a no noise, ta-2a barely audible
Does the buzz mean transformer is on the way out? Or maybe there are other issues that are causing transformer hum/buzz.
Its same buzz you hear on all adcom amps. Like on electric power plant but not as loud. Most nakamichis stasis i had had dead silent transformers.
Basically I might keep the amp and want to perfect it
Sr-4a is nice and clean sounding. But feels underpowered compare to ta3a
For some reason ta-3a is most open and impactfull Sounding. You can feel juices flowing in your veins
Bias is 23mv on both.
On paper sr-4a is superior.. don't understand why doesn't sound as powerful and punchy as ta-3a. Volume matched. Tried everything
These were used with Polk sda crs+ bookshelves, which tend to be power hungry
Ta-4a is a bit bass heavy for me.
These sound signature observations are after having 3 ta-3a, 2 sr-4a, 2 ta-4a.

The buzz is mechanical and is usually loose lamination or incorrect fixing to the chassis. It is not going to fail soon.
Sound more high pitched. Like loose insulation?or lamination.
If I decide to replace it are there any manufacturers i should look for?
Maybe go up in some specs would help. Give extra reserve power. Not run as hot
