?

Not sure, I am not that smart or knowledgable, still learning.

Amp's are Aleph J's which are nearly finished.

Out of interest the complete system will be as follows
Diy Slate and acrylic TT
MY TT build
Dl103R Cart

HPS 5.1 Phono
Hps 5.1

Pumpkin

Aleph J's

4 Way horns
Fane 8m, 200hz LeCleach
Yamaha 6681b 400hz LeCleach
Fostex T500A MKII
Bass TBA

I hope to avoid digital X-Over so am looking at Passive line level for X-Over.

My skills are best used on the hands on building part. The technical side is where I am laccking and slowly learning.

So what gain should I set Pumpkin to and how do I go about working this out.

Cheers

set Pumpie for - say - 4x gain

meaning - input resistors in range of 15K , feedback resistors in range of 62K-68K
