Features:

• Designed for drop in replacement of original units.
• Physically, parts were designed to look similar to original factory units (where possible).
• Inductances measured at rated D.C. current.
• Material used & design specs. were kept as close as possible to the original part to preserve the stock "tone".

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.

• Primary 115 VAC, 60 Hz.
• Secondary 30 C.T.
• Center tapped secondary.
• Open style, channel bracket, two hole chassis mount.
• Minimum 6" long leads.
• Dual bobbin design - no electrostatic shield required.
• Class B insulation (130 degrees, C).
• Hi-Pot test of 2,000 V RMS.
• UL listed (# E50394) & CSA certified (# LR3902).
