Pushpull Amp


Posted on Aug 12, 2012

With all DHT stages (all tubes from Svetlana 1970-s). OK, the input/splitter are not DHT`s but DHP`s - 4P1L - triode wired. Mullard 3-tube input/splitter topology, cap-coupled to cathode bias 6B4G PP. First stage uses battery bias (no cathode resistor). Only paper capacitors everywhere. Gas regulators for the first stage.

Later, I replaced Mullard splitter with IT splitter in a Loftin White arrangement. It has gain about 90 at the second stage plate. Next steps: rewire IT to a step-down ration (right now it`s a stock 1+1:1.25+1.25) and replace first stage load for a G
