I have read here that the SVT-II does sound more vintage than a 2 pro and the preamp section of both amps is different. I also have read that the SVP-CL sounds more vintage than the SVP-PRO which is the preamp circut of the 2 Pro. My question is:
Is the SVP-CL Preamp the same as the one inside the original SVT-II or how different are they?
There are several threads detailing the SVP-CL. To answer your question no, the SVP-CL and the pre in the SVT-II are not the same. There was an SVT-IIP made for a period of time though.
I believe the SVT-II has one more (3) 12AX7s then the SVP-CL's 2.
Here's a comparison of the comparable, listed specs of the tone circuits omitting the ranges not found on both units; ie graphic, ultra low setting and bright that are not found on both units:
SVP-CL ULTRALOW: -20dB @ 600Hz
SVT-II ULTRALOW: -20dB @ 600Hz
SVP-CL ULTRAHIGH: +16dB @ 8kHz
SVT-II ULTRAHIGH: +20dB @ 8KHz Volume Control Dependent
SVP-CL BASS: +17dB / -13dB @ 20Hz
SVT-II BASS: +/-12dB @ 40Hz
SVP-CL/SVT-II (same)
MIDFREQ: +/-20dB @ 220Hz, 450Hz, 800Hz, 1.6kHz, or 3kHz
SVP-CL: TREBLE: +15dB / -20dB @ 7kHz
SVT-II: TREBLE +/-12dB @ 5KHz
The specs won't tell you what they sound like though. In summary they both sound like SVTs. With things set about the same, I'd say the II has a little more high end "air" or brighter or "in your face" treble. The SVP-CL a little more pronounced bass. Like I said in a post above, I've been able to set the II to sound very much like the SVP-CL. A little harder to go the other way though.
The context of this is with the SVP-CL through the power section of the SVT-II. The SVP-CL has whatever tubes came in it. The pre tubes in the SVT-II are old and I have no idea anymore as to what ones are in there.
