100W Ultimate Fidelity Amplifier

[DAMANHURI]

Zeners must be connect to 1k/2W not to rails...

Is it like this?

Is it like this?

Yes, I suggest to change position of bias transistor BC550 with 100nF cap, BC550 must be on heatsink with outputs in thermal connect.

as instructed Mr. Mile, I had my fix for the perfection of design

BDW93C and BDW94C are in TO220 case...

Overload detect is add on AX16, and send +HV on PRO out...

thank you...

 

[apexaudio]

Overload detect is add on AX16, and send +HV on PRO out. This voltage can activate DC protect (like in HV350 PSU7), and disconect speakers if overload detect.

okay thanks mr.mile.

AX-14 Schematic and PCB

the capacitor values in the component layout board are not matching with the schematic (from which you have posted in page 71)

Thank you sir
but C7 has 47pf in schematic but in layout it has 22pf

Thank you sir

Both value will be OK, but use 22pF.

2SK1529 and 2SJ200 can be use for FX14

can i use 2sk1058 and 2sj 162

 

[apexaudio]

can i use 2sk1058 and 2sj 162

No, you can use 2SK1058/2SJ162 with F100 in thread http://www.diyaudio.com/forums/solid-state/162081-dc-servo-mosfet-amplifier-13.html from post #123, pcb in post #156,

thank you so much.

Mile , You told FX-14 will be nice for 2sk1530-2sj201. Do you have pcb layout for this.

No, I use same pcb for AX14 and FX14 with changes from FX14 schematic.

Sir what changes occur by changing this capacitor value

Amp is 'faster'

 

[shreya]

Amp is 'faster'

Sir 'faster' in the sense?

The higher an amp's slew rate, the faster it is!
