Versatile and comfortable passive pre-amp

Ivar, I googled for your TEAC RC-722 remote control unit, but could not find any details concerning the IR protocol that it is using.
Give it a try.

[Rudi_Ratlos]

Ivar, you can use the 100R resistor and need not order the 33R.

Where goes earth wire after iec if vcpre has only two + - inputs?

 

[Rudi_Ratlos]

Ivar, the earth-protect wire is as usually soldered with a short wire to the metal case near the mains input connector.

i know it is ac, but is there designated hot and neutral on board input?

 

[voxxonline]

Tested board. Psu Works. Lcd turns on. No sensor, ldr, relays installed. My lcd shines but No text just solid bright screen. What did i do wrong ?

The 1st mistake that I see is that you connected the LCD connector cable in the wrong way.
The GND connection (Pin 1, red wire) must be on the right side of the LCD's connector, not on the left one.

I received the LDRs from Uriah yesterday, put them into your letters and will take your letters to the post-office tomorrow.
You should then all have your orders by the end of this week.

Gentlemen: I could not resist and built two VCPre - PCBs for a close DIY-friend of mine on the last weekend (see attached Image).

Both VCPre - PCBs work from the scratch, offering you a large versatility and comfort - giving you a gem of a low-cost, hard to beat
sounding and comfortable (every function can be controlled remotely) passive pre-amplifier.

Best regards - Rudi_Ratlos

P.S. The temperature sensors have not been connected yet.

Almost finished. Just a little bit more internal wiring to complete 🙂
