![]() It would be very nice to have some feedbacks, especially about my routing. I almost managed to creat a one-layer board, there is one jumper wire plus the connection to the heater of the ec88 tube where I do not know if I should try to route it, or just sold a twister pair of cables.Īs you see is that for the first time I did not route everything 45 and 90° which is really new to me. The two tube sockets will be soldered to the bottom layer, all other components will be placed on top. The looks will be similar to the bottlehead crack amp, wood panels and a top plate with just 2 tubes and the transformer (in my case a toroidal one) It is called "6as7 mini OTL" on the website, and the author has links to the schematics of the power section and on the amp.īased on those I am about creating a PCB board with the dimensions of 230X140mm which will also be the dimensions of the top plate of that amp. After many boards with all digital schematics (another part of the hobby) with lot's of small pcb traces I wanted to work on something else and here it is: New OTL headphone project with 6SN7 and 6AS7Īfter two nice builds from PCB boards of Pete Millett I wanted to start a new project, this time with a PCB board by myself.
