- Notes
-
On MP-200 are mounted a new type moulded tube receptacle, a new type smooth-running filament rheostat, a standatd amplifying transformer, two telephone jacks.
Plugging the phones into one jack gives unamplified signals and into the other amplified signals.
The panel of MP-200 is so designed that other steps of amplification may be set beside it without the creation of howling due to reaction between the fields of amplifying transformers.
Two of these panels comprise a neat, efficient two-step amplifier.
