These units are extremely fully impregnated and sealed in adrawn housing. Most items provide fre-quency response within 1 db. from 30 to20,000 cycles. Maximum operating level0 db. These units are also available inour stock P series which provide plug-inbase. The 0-16 is a new line to grid trans-former using two heavy gaupe hiper-malloy shields for high hum shielding.
