Hello,

Just finished building my home made 18 Watt amp. The amp works fine but only when i donīt used the tube V3 for the cathode follower. When i put the V3 in the amp the amp start to oscilate. I swapped the V1 and V3 tube but no results so i think the tube is fine. I checked also the wiring but seem to me that that is also oke.

When i play without the V3 in the amp everything seems to work fine. Only a little hum. Of course i can only used the input 1.

It should be fine if some here can help me a little bit to solve this problem.

Problem solved. Rewired the output transformator and ready to rock.

It's sound great at the moment.
