Jungson Ja-2 pre amp

Attached is a few shots of both the dual and single discrete opamps in my Jungson Ja-2 pre amplifier.
The change in sound wasn’t subtle. This was a relatively straight forward exercise.
They are slotted nicely in some sockets installed for opamp rolling purposes.
An excellent upgrade from the BB2604 and NE5534’s.
They match nicely with the Siemens ECC801s tubes.

Kind regards
