Hello Friend please some one give me the TB3 tone control PCB Pdf file willing to build one thanku
figured out why my apex psu protection board wasn't working. It was a BC546 that was faulty (brand new).
After replacement, the output short circuit protection works (it triggers at about 3.5 amps drawn on the rails, 2x60v power supply), however the dc output protection is not. I've changed the dc offset of my amp (apex ax17) to output about 7 volts dc, however the relay hasn't disconnected the output.
What is the dc minimum value at output needed for the protection to kick in?

Apex fh9 xrk mode
Hi to all!
I finally finished APEX FH9 XRK mode last night, everything went without hickups and with no smoke 🙂.
Sound is awesome, bass is great and details are very close to my JLH 1969 so I'm very pleased. I think it is more suitable to modern type of electronic music than JLH, but I need more listening time for finall impressions. I made it partly with scrap electronics, IRFP devices are new, bought on ebay and housing is from old Antec Phantom series PC PSU. PCBs are home made. I use external 2x22V PSU for now. Thx to mr. Mile, XRK and Sonal Kunal for this great little amp!

Hi strawa,
are you about achieving a Darwin award? You've used the wrong IEC inlet!!
Best regards!

Thx guys!
That inlet is standard in my home 🙂
I'm using it for connection to my external power supply, not for 220V. Salvaged from computer PSU.

I think both of you are refering to 220V inlet - as you can see in pictures there is no tranformer nor any other 220V device in the box. I simply use that inlet to connect to my 2x22V amp power supply, so no worry here. Not commercial product hehe.

Misters. Whether there is at exact also a working scheme APEX P30ZF, and also working PCB for him? There is a wish to try to collect. Whether working this decision? And if there is information on him share. Excuse for my English...

execuse me guys ...but what is the supply voltage for A33 and the output power and input sensitivity
thanx
thanx
Hi sir do you have the schematic and pcb for this selector? Thanks in advance!
