100W Ultimate Fidelity Amplifier

Eagle files for the apex b50 amp.

Always buzy! 😉

Yes !! This is a good chain conection. But you should put the switche, if you want to do a bypass. If you want to take out the tone control TB3.

Very thanks kandimba, for your suggestion!

Which layout have you tried?

all these. these are all mixd up

That is the one I built and it works fine. Not sure what the problem you are having might be. There is another previous layout that also works. I see if I can find that one.

Juan Vargas also designed a two sided board that I believe he shared the gerber files for.

Here is the layout provided by Alex. It had a few extra holes to provide for different style components.

I found a couple of errors. I have fixed them. You should be able to fix your boards by just these changes.

The P30 will be the pre amp for my sr150. Are there important differences between P30 and P30zf?

I didn't build the P30ZF so I can't say. The P30 is very nice!

Here is a picture of my completed P30 preamp. All Apex except for the Volume board and the switchable output board.

Blessings, Terry

Hello sir,
Can I use without changes AX14 with 10 pair on +/-90volt rail voltage

 

[Sainirahul780]

VAS from AX-14 can work with +/-120V DC rail voltage without change, with output stage upgrade U can get 500W/8R. I also use MOSFETs for some versions...
I made this class H version ' Ultimate 500' for test, and work great with +/-120V,+/-60V,0V rail votages.
Regards

Sir pls share this circuit files
