CUSTOM BOARDS  

"Custom board with Gold Plated Pins!" 

This is a sure winner with a multitude of applications. This board was 
used to build a complete phono and line stage with a tube power supply!. 
Hi-End quality and superb durability.

 

"Custom Board for stereo Push-Pull Amplifier"

 

                                                                                                                               

"Custom Board for Transcendent Sound's High Power OTL Amp"                       

This application is the ultimate test of the reliability and durability of
the point-to-point FR-4 boards. The schematic above, though fairly complex was
built quite easily using a custom board. Shown are bus-bars connecting 8 output
tubes(EL509)and a ground plane. The amazing ease of construction made building fun.
 
Something has to said about the heat resistance if this board. We all know
how much heat is dissipated in OTL amplifiers. After long hours of use, this board
showed no signs of heat stress. No flexing visible when inserting or removing tubes.
Rock Solid!
 
Custom copper clad boards are priced at $0.60 / per square inch (without sockets). 
For non copper clad it is $0.45. To order a custom board, contact us to discuss layout. 
Your layout should include board dimensions and an X Y coordinate for each pin and 
socket. If you fax a full-scale layout, your drawing might be scaled on some fax 
machines!.
