Output Transformer Question Please
02/14/19 at 16:03:45
 
I am a self-taught newbish amp builder and I ordered the board to build the SE amp. I am not the strongest with calculating the specs for a output transformer, so I was wondering if this OT would be an appropriate substitute for the EDCOR units recommended for the build.

Specs:

SE - 10W
8 K with 40 % UL Tap to 8 & 16 ohms
Frequency Response: 20 Hz to 80 kHz +/- 1 dB @ 1 Watt

Maximum DC Bias Current: 75 mA

Primary DC Resistance: 400 ohm

Primary Inductance: 50 H @ 120 Hz

Many thanks in advance...
Nate

If the 1st watt
sucks why continue?

Hello Nate,

Sorry for the delay in seeing this!

Your output transformer would be just fine.  You simply wouldn't use the ultra-linear taps... or you could use them in place of the 1K 2W resistor on each output tube, your choice.
