Hello,
The push-pull is singing for the first tome this evening. It works great.
I wind the interstage transformer.
2100 turns of 0.1mm enameled wire (something like 38 AWG for you)
and 2 secondaries of 5250 turns each, with the same wire.
FOr the output transformer, I know... It's a shame... I use a power transformer
I left the primaries unwired, I only use the secondaries.
The speaker is on the 6,3V filaments winding. And I use the 2 high voltage winding of 2 x 280V for the primaries. It works fine. The sound is very loud and clear. With an ohmeter, I see 680 ohms with these 2 winding, like the schematics. That's great.
Everything is working right. lot of works but it was worth it.
Now, I've to work on the cabinet.... But after the holidays :-)
Best regards
