It might be useful to state that the 4P1L preamp I've built has a gain of 8dB and an output impedance of about 300 ohms with an LL1692A (3.75:1) as a line output transformer at the operating point I am currently using (150VDC plate voltage and 18mA). That amount of gain is good for me under the current circumstances, but it can be modified using different operating points or a different line output transformer turns ratios.
