I forgot to mention something: With the upgraded output transformer option, we'll throw in a hefty filter choke. The amp will easily compete against ones costing $2,500 and up. With that in mind, you're saving at least $1,000 relative to an amp of the same caliber.
Total weight with all upgrades: 45lbs! Remember, you get to choose either Edor or Hammond Outputs. If you would like a third option, I can install 15 watt One Electron outputs, I have used these as well and their quality is outrageously good. Upgrade price remains the same for the One Electron outputs.
