Is the 2 Channel "H" different than what I have?

Well I have an "H" combo. Snagged it off GC used for a great price. I've had it over a year, but it's never left the music room. When I venture that, I will know how it sits in the band mix. I reserve judgement on amps until that happens. I like what I hear in the house.
It's a good amp. Gigged it for years and still have it.
