RE: DHT 01a tube preamp




With an output impedance of 330K playing into 175pf the -3db point of the low pass filter will be 2756Hz. The -1db point will be at 1378Hz.

That is a massive lose of high frequencies and it is only going to get worse when you add in the Miller capacitance of the first stage of your power amp.
