No such thing as free gain. HA-108 is not designed for IT with high Rp tube. Low Source Z of around 600 requires Rp lower than 600 or so for the ideal condition. What driver tube are you using? You mentioned lower source than 900 ohms? But are you already maxed out on the driver plate current for the current driver tube Rp?
Tube IT are supposed to have higher Primary Z not to load the driver tube or the power is wasted on the primary side.
