pearl phono

Hi,
could anybody out there help me with pin out information for the devices in the pearl phono amp. I intend to build the gain stages first and then build the power supply stuff afterwards. One bite at a time.
I have previously built pro-audio clones- 1176, ssl,etc. and a few little toys of my own, but I am struggling to find the information for the ztx 450, 2sk170 and 2sk389.
I intend to lay the components on stripboard and try different means of grounding- shielding. If anybody has advice about this I would greatly appreciate it.
Great site! The wiki's are great!

Cheers.

Google is your friend. Search for the datasheets, they have all the info you need, included the pinout.

The input JFET's may be important but the other bipolar ones may be changed to just about any small signal transistor with sufficient ratings, not very critical.
