Help fine tuning tube preamp build

[sonolink]

Is that with or without MosFET? A source follower normally needs more current...

Without the source follower

Perhaps these are artifacts of the NE555 PSU. I was never satisfied with this type of PSU. Maybe it's just me, but there are better solutions, even for pedals.

Really? Can you point me out to some please?

Sorry Sono, somehow I overlooked your question.

In my opinion, this PSU solution is much better and more flexible than the 555 circuit. I have tried both and in direct comparison this one is preferable. With a little extra filtering you can achieve a very good quality HT voltage.

Have also a look at this and that.

The only thing you should avoid is close proximity to transducers, pickups and unshielded signal transformers.
