6N2P Tube Pre-Tone Low Volt & Low Cost Circuit Diagram, I would like to present the low voltage and low cost for beginner developer. This is the kind 6n2p Triode Vacuum Tube Russia Tube very cheap compared to other tube models. Only cost $ 10-15 for a true beginner. Also easy to find in the market .

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 schema 741. But output is not satisfactory offline … hum a lot. Experimental values ​​are being changed. To complete the schema. Before, and I will be published offline because many people complained that the transformer is quite difficult to find ideas to this schema.

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.

Build a Low Cost Line Receiver Circuit Diagram. This is a simple low cost line receiver schema diagram. This timer makes an excellent line receiver for control applications involving relatively slow electromechanical devices. It can work without special drivers over single, unshielded lines.
