good sr mile
can you help me with this detail
regards

Do not use this resistor, there is resistor on TB3 input.

Mr. Mile,
Thanks. Here is a compact minimalist version of your softstart with 24V relay that can be placed between switch and trafo.

Thank you!

sure PM your e-mail and I'll send it to ya no problem yes I called "Golosa" but is just AX-14 with more pairs



Best Regards
Juan

Sir Juan can you share the schematic diagram of your Golosa sir thanks

APEX DC555s stereo protect with fan control

have you solved an issue with a40?

 

[maxwell007]

not yet...only one channel is OK and working well...i have no time

 

[44250]

i was solving a bias problem today - solution was to use driver transistors as assigned in schematic instead MJE15045-45 wich i used. now i have to assemble one more pcb...and enjoy at last!

What about PSU. Can u tell me

 

[44250]

for stereo,at least 750VA transformer with 2x44Vac secondary.

Hello brother 44*1,41=62.4 it's ac after dc.but all capacitor is 63 volt.its too high.mean 63 volt capacitor we give 62 volt.you know what I say?

 

[44250]

actually it will be +/-60V,there is 0,7V on each of two diodes in bridge rectifier. use 2x42Vac,or buy 75V capacitors.

i want fx9 pcb .please suggest me.using 0ne pair irf224 and 9240
thanks

Hi Scott


may this new routed Board will work for your need.
It is mostly followed by Sonal traces, but added above traces.
Have fun.
I place my orders to KiKiPCB, like vargasmongo.


Regards.

please send me in pdf form
thanks

No one recognise this?
At least, those 10% donated should go to the right person.
