The LS 99 uses the same topology of transformer-coupled inputs and outputs, a tube rectifier, and SS stabilized power supplies with (2) 6922 driver lamps. The power supply is external, but not dual mono, like the LS 300.

LS 300 Balanced Tube Preamplifier is a tube preamp with an external power supply and a dual monoconstructure.

If we talk about the functionality of the ModWright Instruments LS 100, then it is quite expected from a device of this class – nothing superfluous and no settings. All the functionality is configured exclusively for the various switching capabilities of the preamplifier. Both RCA and XLR connectors are available to the owner of the device, but despite the presence of the latter, the LS 100 preamp is not symmetrical, but only allows you to connect symmetrical sources to it (if they do not have RCA output connectors).
