    PILOT SA 232 WITH 6L6 AS OUTPUTS

    Hello everyone, I'm pondering on building me push pull amp with 6l6gc as the outputs and using the pilot sa 232 topology as the gain and driver stage. Is this doable or just scratch it? I've drawn up a mock up schematic and please feel free to correct and criticize. I would greatly appreciate...

    Baldwin Amp Quesrtions

    Hi Battradio, You know what, I like how it sounds without the 100pf cap on the 12ax7. It sounds more alive and dynamic. It doesn't sound rough nor dirty at all. It still sounds smooth. I like it. Is there any detrimental effects leaving this cap off the circuit? Regards,

    Baldwin Amp Quesrtions

    Hello, Moved the 100pf cap to pin 1 of 12ax7 and it sounds more alive compared to when connected to pin 6. On pin 6, it sounds like the mid is and highs are a bit dark or dull sounding. On pin 1 its more alive, airy and dynamic. Also tried without the cap on pin 1 or pin 6, the sound is more...

    Baldwin Amp Quesrtions

    Hi Mike, I have completed the rework. And i am shocked as to how good these amps sounds. They are wonderful. Very musical and engaging amps. They are keepers for sure. I prefer the higher screen voltage as well. Tried the lower screen voltage and it wasn't musical at all. I'll try to move the...

    Baldwin Amp Quesrtions

    Hi Mike, I have a few more questions 1. Which pin of the 12ax7 do you connect the 100pf caps? On pin 1 or pin 6? What does this cap do? 2. Have you tried the lower screen voltage and if so how does it compare to the higher screen voltage. Please correct me if im wrong, the higher screen...

    Baldwin Amp Quesrtions

    Hi Mike, Thank you for the input. When i get back home later, i will change the 200ohm on cathodes to 250 ohms. My operating points will be about 380v on plate, 370v on screen with 250ohm cathode resistor. I'll see if i have any suitable chokes to use for the power supply. Do you use a...

    Baldwin Amp Quesrtions

    Hi battradio, I appreciate your response. Just to clarify, your screen voltage for the output tubes is at 370v instead of 320v and used 250ohm cathode resistor. Have you tried biasing using the 200 ohm for the cathodes with 370v on screen? Im asking because the schematic says to use 200 ohm...

    Hi guys, Hopefully we could resurrect this thread. I have the same amp and have identical pedal output trans. Now my question is, which does sound better based on the schematic drawn by secret4mula. Im leaning towards building the the one biased higher for more power. But which one sounds...
