I ran across that one before. An interesting amp.
what changes? How does it sound? OPT primary impedance? Power?

Hi, Dave!
Changes: nothing special, just tuning; power supply is: Hammond 272BX + 5Y3GT + Hammond 193C + 470uF + 3K + 470uF; output transformers are Hammond 1620 (20W, 6.6K, secondary connection for 4Ohm).
Sound is natural, better then I expected. No hum at all (1-2 mV).
Power up to 3.5W; 2W without visible (on OS-5020G) distortions.
Almost finished: parafeed 6C45PI+300B
Hello,
That is not finished, but that is my first attempt to utilise DHT.
6C45PE as a driver in parafeed and 300B in parafeed too.
Static voltages - OK, weight now 20kg (about 40 lbs)
Tomorrow I am checking dynamic characteristics. See attached pic.
