is it possible to use 2 small trannies instead of a big one?

    one of the things the studio versions lack is the punch of their big brothers. The SV they are great amps, don't get me wrong, but I wonder if they could use three small transformers, get a better punch/bass, and keep the studio version in the same lunchbox format?

    no transistors, only tubes.

    That’s how they did the JTM45/100 Super Amplifier. Two 50 watters instead of a 100.

    @EJstrat&JVM, what exactly are you referring to by 'punch' - do you mean strictly bass response?
    If that's the case then maybe the current format of the SC20/SV20 work better for some types of music than others. The cutting mids and highs of the SC20 work really well for the punk and hardcore I play, but maybe someone playing metal would like more low end thump?

    No metal, only rock or heavy rock. I would say strictly bass IMO. I read somewhere that when using small transformers is basically impossible to get the same bass (or punch as someone describe it), and it's not a wattage problem, it depends just on the transformer size.

    I stick with bona fide females, but yes two smaller ones are preferred over one big one. Wait! Are you talking about transformers?

    Well yes, that’s correct, but I’m pretty sure they’re talking about BIG transformers. Like the ones in the 100 watt Marshalls.

    I’m actually guessing here and I could be completely wrong but, I don’t believe that two small transformers would have the punch of a single big transformer that’s in a 100 watt amp.

    Those big transformers is where the “punch” is, not 2 small transformers,...unless I’m missing something?

    This is why I prefer a 100w amp over a 50w one. Thats why they call it the “big iron sound”. It’s not more power, it’s a punchier sound.

    When I first tried out my SC20H I used a DOD250 out front as boost (level only, no gain) and with this setting it injected a lot of bass into my signal and I got quite a bit of thump from my 2x12 as a result, even at moderate volume. It worked well for the song I was playing but usually I don't need that much 'thump' so now I mainly use an SD-1 instead.

    I may be wrong, since I'm not an electrical engineer, but maybe what some are referring to is the fact that a much larger transformer can supply higher current to the connected speakers and therefore drive them harder to create the 'thump'. But this would probably only be apparent at higher volumes, not something you will notice at home. Maybe someone with an electronics background can weigh in here?

    Yes, when I was younger (and not married), I always preferred two smaller females over 'one big one'. :lol:

    Wait a minute...what is 'bone fide'?? :scratch:

    I believe I've read some theories here that the smaller transformer was used in the SV20 and SV20 to help reduce the power output and the volume of the amps. This thread brings up an interesting question, I don't know if it's been discussed elsewhere since I don't have one of these amps. Could you install a bigger transformer in one of these amps and get more out of these amps? Just thinking out loud here.

    I describe punch as power to move air. Not gas .lol
    Anyway my experience with that was going from the JCM 900 DR 100w (very loud),with lots on punch to the DSL 40CR and to me had no punch. But guys here have modded the DSL with better output transformer’s so that might make the “punch” harder.

    Ah, the auto-correct feature in my phone has struck again. It's not too keen on Latin. I typed bona fide.
