yohnsee where can i get a case like your or is it a salvage????? any online way to buy one
Hy! It was an old amplifier's case, but the front panel didn't fit with the cooling fan and the heatsinks, so i made a new one. The rest of it was a Reflex 500 amp's case.
Hello Apex !
I have read most of this thread today and saw some changes made. And I was wondering if you could make a complete pdf with all the new components, PSU, Bridge board, PCB's... I think that would help many other so they don't need to search the 137 pages for the latest version.
So I want to make this amp could you recommend the best Input voltage ?
Thank You Very Much.

Thanks for the reply sir
Thanks for the reply sir
I'm sure, that you either can find a case in the garbage (if you know where to look) or find a friend, who has a metal bender, so you can make your own case. It's really not that difficult, just plan before you make anything, and the result will be satisfying.
Sir Apex,
Can I use B500 with a DC supply rail of 100V-0-100V..? and what changes should be made...please help me...
Use triple darlington topology and 8 pairs of outputs.
Hello,
I have assembled most of the parts for B-500. Transistors yet to be soldered.
I will be using Regulated Psu giving 75-0-75 dc, and 4-10,000 mfd capacitors, Do i need to make any changes.
Currently i am having 37-0-37 5 amps transformer, Can i use this to test the amp.
The heat sink is 15" long height 105mm and fins length 44mm, I suppose this should be enough.
Will kse350 work in place of mje350.
I am assembling a amp for first time without any help, So tell me how to set bias for the transistors. And what initial steps to take for testing the amp.
I am not getting relay for protect, can i get any photo of the sample or link where to buy it in India, is it fine if i connect the speakers without protect.
hoping for the big miracle.
Thank You

check value of 5 watt resistors AGAIN
They are 0.33r 5watts , is anything wrong.
if i need 250watts rms at 4 ohms what changes should i do.
sorry viki looked like 33ohms
Ok Thank you.
Please give guidance for first startup and bias adjustment.
I am not having good electronic experience, so some guidance is welcome.
