This is a blank PCB for construction of a DC power supply for a tube amp.  It can be configured other ways (see the schematic and PCB picture) but I use this to generate three voltages, a plate voltage, a screen voltage, and a negative bias voltage from a center-tapped winding plus a floating bias winding.  This application is shown on my web site here.  eBay will not allow me to post the link here any longer, so you will need to do a web search.
It mounts to the chassis via 6 holes.  Screws and standoffs are NOT included.
This auction is for one PCB only, no parts or anything else is included.   Photo of assembled PCB is for reference only!  
Will ship anywhere.  Flat rate shipping is shown, additional PCBs ship for free.  Payment by PayPal only.
