DIY PCB – Push-pull tube amp driver PCB

This is SINGLE blank PCB to build a push-pull monoblock tube power amplifier, using a variety of output tubes like the EL34, 6L6, and KT88. For full details on the amplifier design, including pictures, measurements, schematics, bill of materials, mechanical drawings, etc. refer to my web site . eBay will not allow me to post the link here any longer, so you will need to do a web search. The PCB has the input and driver circuits and the bias supply on it – the output tubes and main power supply are mounted off-board. It is a very flexible design, using a single triode first stage, and a differential amp pentode second stage. The first stage can be bypassed if not needed. NFB can be provided to the first or second stages if desired. Note that this project does involve contruction of high-voltage circuitry, so do not undertake this unless you are qualified and comfortable building circuits that use dangerous voltages! This auction is for is one PCB only , no parts or anything else is included. Will ship anywhere. Flat rate shipping via FedEx to US destinations is shown.
