500W PA amplifier with Limiter

[kandimba]

P { margin-bottom: 0.21cm; } [FONT=Verdana, sans-serif]I Mister Mile, I Have a power suply from an old Inter M amplifier CM20.5, this unit give +135 VDC / -135 VDC. Can I do the Apex B2000 ? If I can, tel me please the volts of blue, red and green condensers. Thanks in advance.[/FONT]

This is just idea,

B700 simulation was succesfully done. I will work with some fine tuning...

Any Idea what the projected supply rails will be?

Any Idea what the projected supply rails will be?

The simulation was done with +/-85V. I think this is the maximum safe voltage with 100V psu capacitors. The simulation gives about 1000-1100W/2ohms.

Any way that it can be run off +/- 96v rails. I only need a minimum 4Ohm load? I already have the PSU from an old amp. are there PCB's / PCB designs available?

You can try it, of course, but I would not recommend.

ba1200 xlr input

good day mr. mile, can BA1200 xlr input be use in b500? if can, any changes?

Yes it can be use without any changes.

Good day,,newbie here..
Sir apex, what specs of psu and no of pairs of trannis to be use to produce a 500 watts. I backread but im confused...i like to build your amp..TIA.

apex 500tef

hi apex sir,can b500 tef with 8 pairs face 2 ohm load with +-85v dc.i need 2 ohm amp and how much watte. please suggest me

About 1000W/2R with 8 pairs.

Good day to all,,can anybody tell me were to connect the a and b in the input side of the b500 circuit? Thank you very much.

when you plan to bridge the power amp then use the a and b, there is schematic for bridging power amp read to understand from the start of this thread.🙂

Hello sir , I build b500 with psu7 56V AC but noise from fan. I use another psu -24Vdc no noise

. Thanks Apex.

ONCE AGAIN THANKS TO SIR APEX AND SIR WILLY MY B500 TEF... GREAT SOUND ...

B500 tef 8 pairs
Sir mile iwant to build B500 TEF 8 PAIRS Sir this layout is ok sir? thank you so much sir Mile Advance merry x mas sir..
