It happens more often than you want to believe and in both directions. I've used 100K where I needed 1K and vice versa. You have to check every resistor on the meter two times before you put it in the circuit. Sometimes, what you "see" and what the meter reads are two different things.flood wrote:it turns out that instead of putting a 220k resistor for the V1 plates, i'd used a 2k2 instead.
Those clips sound good to me. If you need to reduce the treble, try using some different value caps in the tone stack or increase the value of the bypass cap on the first gain stage. If there is no cathode bypass cap on the first triode, try a variety of caps... .68u, .1u, 5u, 10u, 20u. As you increase, it will let in more bass.
