Hi all, Today was the magic day of plugging in the power cable and switching it on for the first time. To say I was nervous was an understatement. Amazingly, the house did not disappear in a flash of flame and smoke, just a little burst of light from the dim bulb limiter when flicking it off Standby. No bangs, no smoke, no drama. To say I am delighted is putting it mildly. I spent a while measuring the various voltages with no tubes, then put in the Preamp tubes and re-measured. Do the voltages look reasonable? Rectifier in voltage = 601Vac, rectifier out = 446Vdc. The amp was built from a Modulus Amplification kit (their MOD800 kit), with a few tweaks: 1. Switchable bright cap 2. Treble peaker reduced from 500pF to 330pF 3. V1a cathode resistor = 8.2k I will be posting some build photos and adding more info about the build shortly.
