HAMMOND
"CLASSIC"
SINGLE ENDED ULTRA-LINEAR OUTPUT TRANSFORMERS
Key Features of Hammond's Single Ended Ultra-Linear Output Transformers:
NEW & IMPROVED versions, higher power handling, smoother frequency response, two new impedances added & easy to use secondary taps.
Over designed for single ended, Class-A, tube output circuits (triode, tetrode or pentode tubes).
Enclosed (shielded), 4 slot, chassis Type "X" mounting.
Frequency response at least 20 Hz. to 20 Khz. at full rated power (+/- 1 db max. ref. 1 Khz.)
Insulated flexible leads 8" min.
For maximum versatility, all units (except Hammond's 1642SE & 1638SEA) include a 40% screen tap for Ultra-Linear operation (if desired). The Hammond 1642SE & 1638SEA do NOT include this screen tap as they were designed principally for high impedance triode tubes..
High quality laminations, (M6) grain oriented silicon steel
Core is gapped to reduce core saturation in Class-A circuits.
For general purpose or replacement use in single ended tube output circuits, see Hammond's 125SE series.
| Please note that we have adjusted our prices on all of the Hammond Manufacturing products. On May 19th, 2008, Hammond adjusted the prices on all of their products for the 3rd time since the Radio Daze Catalog 306 was published. We held our pricing until this most recent increase. We feel that you will still find our new prices to be very competitive. |

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. A tube manual or tube manufacturer's technical data sheets should be consulted
first, before making a decision on a proper output transformer.

The 1642SE & 1638SEA do not include a primary screen tap (as they are designed for triode applications).
