New project on 807
Hi (hola), i am finishing my first DIY tube amp ( leak stereo 20, photos add coming soon) thanks for your help and start a new proyect. I choose the 807 (is very nice for me) and i have 9 of them, what are the best schematic choice for start. Remember i am newbie.
You can have a look at 6L6 circuits which are far more common.
The main thing to remember using penthodes in the output is that they really benefit quite audibly from a stabilized screen supply.
Here's plenty for you to look at:
I built a push-pull 807 amp, sounds very good and has a lot of power (with fixed bias, can be 50W)
You can also build a single ended amp, will have about 8 watts, less in triode mode.
However it depends on the output transformers you can get- if you have a set of PP or SE transformers, go wiht them.
Thanks, the 6L6 circuits only or kt 88 too?, and what kind a mods (sorry my english) are applied over this circuits to set the 807 tube. And about the OPT, here the trany are hand made by a technician, only needs the values (i need help whit this item), your hints are welcome every time.
