PCBs for line level applications

Status
Not open for further replies.
Hi,

I offer various small PCBs for line level applications which I designed for my various projects. Schematics and PCB design info are in the dedicated threads. Some info is also in the posts below.

I also offer low noise LDO bipolar PSU PCBs designed to be used with the boards offered here.

Prices:
Input/output selector PCB (info here): 3 Euro
Single op-amp PCB (info here): 4 Euro
Dual op-amp PCB (info here): 5 Euro
OPA1622 PCB (info here, here and here): 5 Euro
DC blocking capacitors PCB (info here) 3 Euro
Volume pot PCB (details in post #2 below): 3 Euro
Block transformer PCB (details in post #3 below): 5 Euro
Talema/Amveco transformer PCB (details in post #4 below): 5 Euro

Shipping worldwide: 4 Euro (registered mail) or 2 Euro (regular mail)
Payment by paypal (buyer pays the fee).
PM if interested.

If you need some boards partially or fully assembled to your specification it can also be arranged.

Regards,
Oleg

Volume potentiometer PCBs

Both PCBs have split signal returns (GNDs) which allows dual mono configuration. If needed the signal returns can be connected together by soldering the jumpers.

Block transformer PCB

The transformer PCB shown below is suitable for Block transformers of 2VA to 8VA power rating and other models with compatible pinout. The board is very compact and does not take much more space than the transformer itself. The PCB has pads for CRC snubber components. The mounting holes are on the 10mm grid. Board size is 5x7cm. The primary connection is permanently set for 230 VAC operation and is not suitable for 115VAC mains.

The assembled transformer boards from posts #3 and #4 are for sale for the cost of parts since I am moving all my line level projects to switching power supplies. These particular transformers were not in use but both have CRC snubbers populated.

PM if interested.

Oleg
