Double Output Stage for ESP project68

leander · 3rd November 2005, 07:36 AM

I`m going to built a double output stage project68...As quoted in the article...........

"the doubled output stage, with Q9, Q10, Q11 and Q12 simply repeated - along with the emitter resistors. Each 1/2 stage has its own zobel network and bypass caps as shown, as this is the arrangement "

Should it be as this shown below ?
Note: I added 2 output diodes on the output to protect power transistors from reverse voltage.

Mastertech, did it ever cross you your mind that you could have tried to help or just simply not post at all instead of making a fool of yourself by ridiculing threadstarter?

The original diagram you have looks correct.

To the poster who thought that this was funny, a trip to the ESP site will show you that this is indeed Rod's design. The doubled output section is shown but is not combined to the driver section.

Yes leander your idea looks fine, I can't understand what mastertech was on about, best ignore him. The output catch diodes are a good mod as well, but they must be powerful devices.

Only thing I'd say is that as a newbie you'd be much better off with a simpler project such as P3a as a first project. So much more to consider in the design of a powerful amp, and so much more to blow up and lose you a lot of money.
