Not a bad idea, the Lunch Box amplifier look. If it was cheaper I would use it.

There's no serious manufacturer of tube based devices that makes stuff with the tubes sticking out in the open... Hi Dirk, Perhaps, since the tubes are somewhat inside the cabinet and do not protrude so much, they can be protected in this way:e Jup... that's the standard boohteek way of thinking th...

If you want to go for a reliable design, move away from the idea the tubes should be visible and fully enclose them. Go figure; There's no serious manufacturer of tube based devices that makes stuff with the tubes sticking out in the open. However, there's loads of boohteek DIY-ers who do because t...

Can you please let me know about any spanish speaking forums? Looks from your responses that you have already breadboarded several topologies for PI and output stages and selected what work best for this design. Regarding this revision on the schematic: I see 3 electrolytics (C1, C2, and C10) conne...

Hola José, Thank for you help and ideas. Gracias :) I was working on designing a SMPS based tube amplifier for a couple of years already. I will share my comments. Also, you can use a single triode phase splitter: [ Image ] This way you have a triode section available for another tasks as dual chann...

There are no square wheels,right. Im just starting out in the DIY forum land, and Im finding my ground. Is Everyone going though all the forums?

Totally into the idea of getting the latest version, and starting a project

The KiCad community is pretty much english speaking right?

Hello All, I am wondering if anyone is using KiCad for drawing schematics and creating PCBs? Its available here: http://kicad-pcb.org On the plus side: - KiCad is free software and open source - Its compatible with all the major operating systems like Windows, Mac OS and a lot of Linux distributions...
