Hi: I'm curious: Has anybody made (or is making) an amp that uses a switchmode power supply with a linear Class AB amp. It would be kind of like an NV400 which used a light switchmode power supply instead of the power transformer.

| Glenn, I'm not sure about the AB statis but I thought the Nashville 1000 was a switch mode power supply. I know it's much lighter than the session 400 I have. Of course the cabinet is about the same size as the Session. |

The NV1000 has a class D (PWM) power amp.
Glenn, are you looking for a combo amp or a rackmount power amp? If you are just looking for a rackmount power amp, QSC makes a few. The old Stewart World 600 was a switching A/B power amp (the 1.2 was a class H). |

| I don't know of any, but, I've considered buying a +/-50V SMPS on Ebay typically offered by some overseas company to use in my Session 400 to drop about 20lbs. |
