Better to ask questions before starting work. Measure twice, cut once.

I like that

Hello gents. I do apologise for being off topic. I saw a video on youtube with TP2 tone control. Can someone please send a link with the post/topic of TP2 ? I have tried to search for it but couldn't find a clue.

Best regards.

Mr. Mile,
with 15VAC-0-15VAC , can we get +12VDC/0/-12VDC with above circuit?
Would BD139 require heatsink for say 30-50mA current?

Regarding this circuit, what will the output voltage be if my input voltage is 45-0-45vac? Is this adjustable?

Its in Russian 🙂


I saw that video on Youtube., Is there a chance of getting the pcb layout for for toner transfer method for the TP2 preamp?

With 15VAC-0-15VAC , you can get +15VDC/0/-15VDC, this is Low Drop Output Regulator. Output voltage can be very close to the DC input voltage.

You can set output from +/-45V to +/-60V with 45-0-45vac input voltage.

Thank you sir, appreciate it. And output current? Is that dependant on input current? I would like to use it on your APEX AX14

Maximum current is 10A, you can use it for AX14 stereo
