Universal primary with taps for 100, 120, 220 or 240 VAC, 50 / 60 Hz. (Except the 260A6 which is 117V, 50/60 Hz only)
Designed for preamps, low power amps, general replacement, test equipment, etc.
Economical, open frame, chassis mount - two hole (.187 dia. = G) channel bracket (figure #1) or four hole mounting (figure #2).
Units include a Faraday shield between the primary and secondary windings. Our electrostatic shield reduces the capacitive coupling from the primary - greatly attenuating higher frequency current coupling to the secondaries.
Minimum 5" long leads.
For more selection check out our P-T300-X series of universal plate & filament transformers.
Small, economical, open, two hole horizontal bracket mount.
Insulated, color coded flexible leads, 4" long minimum
Frequency response 150 Hz. to 15 Khz. (+/- 1 db, reference 1000 Hz.)
When operating at impedances below nominal, power capability and the frequency spectrum are proportionately lower, conversely, at higher impedances power capability and frequency spectrum will be proportionately higher.
Molded powdered iron core.
1-1/4 long axial leads.
High inductance & high current.
L measured at 1 Khz. Inductance: 250 µH20% tolerance
DC resistance ohms: .17
Self Resonant Frequency (MHz): 1.5
Maximum DC current amps: 2.5
Coil diameter (in): .43
Core Length (in): 1.25
The UBT-1 from One Electron is a low-impedance single-ended output transformer intended for parallel combinations of tubes running a B+ voltages of 250 to 325 volts, such as: two or three EL34s (triode connected), three 2A3s, two 300Bs, two 6AS7s, etc., as well as single sweep tubes run in 'enhanced-triode' mode, resulting in 10 to 15 watts of output power.
Designed for drop in replacement of original units.
Physically, parts were designed to look similar to original factory units (where possible).
Material used & design specs. were kept as close as possible to the original part to preserve the stock "tone".
