What front switches are you referring to?

Whoops said:What front switches are you referring to?
Ricardus said:He must mean the +48, Phase, Pad, and High Pass.
Whoops said:maybe not because those are not part of this project
Ricardus said:The SSL 9K pre doesn't have those 4 switches? Mine sure do.
spoontex said:I understand,
is there a project dedicated to a front panel? I see some post that speaks about a Jensen A016 standard preamp input circuitry. It's this one or another one?
Thanks a lot for all the info.
spoontex said:Yes, I read some threads. But sometimes there is a lot of information and it's normal that I have some questions.
Whoops said:This is the JLM Go between, it was the most used input pcb for PAD, POL REV and 48V that people used in this project,
it was what I used in the 8 units I built:

spoontex said:is this a good candidate for the power transformer?
Whoops said:No. It has PCB pins and it has low power.
But this is a good candidate:

spoontex said:How important is the use of shield cable for inputs and outputs on this preamp?
Because I see some photos with standard wire and others with shielded cable.
It's really necessary?
Thanks.
Ricardus said:Can't hurt. I usually run Belden 8451 inside projects like this, but I think I am going to look for something a little more flexible. A similar style wire maybe from Mogami.
spoontex said:Thanks!
I have a lot of problems for finding the 2,2k dual gang rev pot. I contact with Audio Maintenance with no luck, I'm still waiting a response from him.
And I prefer a pot than a resistor rotary switching, that was mentioned in this post.
Anyone can help me with the potentiometer?
