Power and audio output transformers for the "OddWatt - ECC802S SRPP / EL84 (6BQ5) Push-Pull Tube Amp" by Bruce Heran of OddWatt Audio.
The "OddWatt - ECC802S SRPP / EL84 (6BQ5) Push-Pull Tube Amplifier"
A ultra linear class A push-pull valve amplifier using EL84 (6BQ5) tubes designed by Bruce Heran of OddWatt Audio. For more information and schematics see the "OddWatt - ECC802S SRPP / EL84 (6BQ5) Push-Pull Tube Amp" page at diyAudioProjects.com.
The amplifier uses one XPWR105 power transformer. This transformers is a 120V at 60Hz. or 240V at 50/60Hz. line to 360V (180-0-180) at 250mA center tapped and 6.3V at 3A.
The amplifier uses two XC63-0.5H-250mA, 0.5H, 250mA chokes.
Audio Output Transformers
There are two CXPP25-MS-8K audio transformers. This audio output transformer is a 25W, push-pull tube output transformer for 8K Ohms input impedance to 4, 8, and 16 Ohms.
All units are wound with the finest virgin copper magnet wire. All windings use heavy insulated wire to provide excellent manufacturing yield, lower customer cost and superior life.
EDCOR uses the finest M6 line grain oriented steel cores. Each unit is hand stacked to assure at least 92% stack.
Injection molded Nylon 6/6 with the addition of 30%-35% glass fibers. The addition of glass fibers allows a higher heat deflection temperature and it brings the material to a class HB UL temperature classification.
The terminations are UL1015 color coded lead wire.
These transformers comes with steel end bells for mounting with the use of screws. See dimensional drawings on product pages.
