Is it good practice to have the input of the amplifier absolutely not guarded against RF ?
is it good practice to have extremely fast drivers to drive too slow outputs ?
Also 2200ufd in the output will only serve as a memory of the past now days i think far more is needed
Kind regards

Hi,
Me too have built my first amp based on a circuit similar to this one.
The output cap is within the ac feedback loop - this lessen output cap size requirements somewhat. But a small output cap will limit power bandwidth. Better use to use 4700uF or more.

Would it be worth to add the Baxandall diode ?
And a capacitor between the bases of the complementary pair ?

Since the Leak Delta 70 schematic is available in this forum, I don't see the point of posting this, exactly. Unless you are selling PWB's, but the Leak has a variable bias current potentiometer, and this doesn't. I build stuff like this point to point on Nema LE laminate because of the fool-resistant speaker protection, but this circuit is even more basic than djoffe's bias current measuring modification of the ST120.
If you're selling stuff, a link through facebook is a black hole to me. Facebook won't show anything unless you give them your birthdate, and that is a security code to my retirement accounts, I don't give that away. People will have to pay a credit bureau to get my birthdate, the one that floats around the internet is a fake. To sell things try Amazom.com, they don't require an up to date computer to participate, nor a pay-pal account like e-bay. And Amazon's list of credit card numbers hasn't hit the news has having been hacked and sold, yet.

This amp is very different compare to Leak Delta 70. I don't selling stuff, you must diy PWB's for this amp 🙂

You can use BD241/242, TIP31/32... if you want slow drivers, and 6800uF/50V can fit on this PCB if you want (25mm diametar)

Hello Hugh, yes it did and i have very fond memories with this type amps, i am going to revisit it in the future when i can...😀
i still have one old setup that needs recapping and reviving...
