Borg7x9, it should not be that big a deal to change the input impedance of the amp. It may be that it has an input transformer- this is not all that strange in the world of SETs. It might be that the transformer has to be replaced. That is not all that hard- I am sure Lundahl or Jensen makes a suitable transformer.
If the input impedance is set by a resistor it will be a piece of cake!
Our preamps can drive higher impedances with no worries.
