Hammond Single Ended Tube Output Transformers - (1627

"CLASSIC" SINGLE ENDED

ULTRA-LINEAR TUBE OUTPUT

Key Features:

Over designed for single ended tube output circuits (triode, tetrode or pentode tubes).
For general purpose or replacement use in single ended tube output circuits see our 125SE series.
Enclosed (shielded), 4 slot, above chassis Type "X" mounting, both end bells include knockouts for optional above chassis wiring.
Frequency response at least 20 Hz. to 20 Khz. at full rated power (+/- 1 db max. ref. 1 Khz.)
Insulated flexible leads 8" min.
All units (except the 1642SE) include a 40% screen tap for Ultra-Linear operation (if desired). The 1642SE does NOT include this screen tap.
High quality laminations, (M6) grain oriented silicon steel

Notes: The above examples of possible combinations are to help you narrow down the choices of transformers for your favorite tube types. How you operate the tubes (ultra-linear, class, B+, bias, operating points, etc.) will change optimum plate load impedance. Only a few of the most popular tubes are shown. As more tubes become available we will add them to the list.
A tube manual or tube manufacturer's technical data sheets should be consulted first, before making a decision on a proper output transformer.

***Secondary Connections***

Note: The 1642SE does not include a primary screen tap. It also uses easy hook up secondary taps (ie...16 ohm full winding with taps at 4 and 8 ohms).
