Good afternoon.
Recently bought a basic Nord 1et400a.
Looked inside, there are rev d buffers, but without voltage regulators. Instead, the jumper is simply soldered.
What do you think, if I buy Sparkos ss78 (15v) and ss79 (-15v) separately and just install them? There is a photo buffer on the nord website (without opamp).
In my amplifier, they look the same, only with opa 1612 and without voltage regulators. The name on the board is exactly the same.

It seems that it looks easy. Opa 1612 suits me perfectly, but regulators are probably better to install.


P.S. Sorry for my english, I am using google translator.
