The quality of their own personal thoughts of my own. Well honestly say that sometimes can get resistant. Instead of a 12AX7 plugged it by changing the pressure tube, topped only cycle . I try to create this Use only one tube. Working as a stereo (two halves of a single lamp), using low power as well.
That if one wants to create a high fire. Put values as I get it offline because I reference values from the Data Sheet.
But do not suggest we fire up to 250 Volts Capacitor find the 350v. The price is expensive and over again.
I recommend creating a 230v. And then use the Cap 250 v. easy to find cheap used instead of the sound was no difference between voltage 250 to 230.
The trial was a pre-tone light bulb with + – 35 Volts with the famous circuit 741. But output is not satisfactory offline … hum a lot. Experimental values are being changed. To complete the circuit. Before, and I will be published offline because many people complained that the transformer is quite difficult to find ideas to this circuit.
I do, then listen to the sound does not make sense at first, it offline. Central held very outstanding voice .. much agitation. But keep it open for a few days … to draw a lot more sense … mixing different sounds much less. Really listen. Voice is getting better offline …. now I’m comparing 12AX7. 6DJ8 6N2P 6N23P them on . wait a minute per well offline. Pictures show that I was to hear of the TDA2030 OTL 30watt.
