Amp schematic for Sovtek/Svetlana tubes


2011-01-19 7:46 am
Hi. I have some spare time in the office the next weeks and would like to start a new tube amp project by designing a PCB board of a nice amp (I don't have the competence to design the amp circuit myself)

The amp should have something around 15-20W (stereo, no monoblocks). I would like to use Svetlana or Sovtek tubes as my idea is to give the amp a "russian" touch. well this is only in the head.

If possible I would like to have an "odd" number of tubes, so for example one tube on the power supply part. May sound a bit weird but it is also with the overall design in mind.

Some schematics for working amps will be greatly welcomed :)

Thanks and best regards
