Default Modelling in Multisim - Need Help

Hi people,

I'm a newbie on electronics who is trying to learn and progress. What I want to do is model my current pre-amplifier (which is a Counterpoint SA-5.1) and increase my understanding what's going inside. When I make a good working model, than I want to see the effects of changes on the circuit.

Well, my amplifier has 6DJ8, 6CA4, 6JC6A and 5651 tubes. There is a pre-defined component for 6DJ8 tubes but not for others. I searched on internet and couldn't find any pre-defined data for these tubes. Could you help me on this issue?

There are more component based questions, but let's see the bigger picture first:

These are the PSU and Voltage Regulator schematics of the pre:

SA-5.1 PSU 2.jpg

And these are the line level and RIAA sections:

Now, what I did is combining all these schematics in one model:

Is this the preferable method of working?
