I traded the preamps out to JJ's but I was wondering what everyone is using for power tubes? The amp seems a touch more trebley that I like. I have a set of KT77's and a set of E34L's to try. I'm looking for a smooth, British mid type sound with creamy highs and pronounced bass. What are you all using in the YCS50's?

Do you NEED new power tubes?

I guess I would go with the EL34s. I'm not super familiar with these amps but I have played 2 of them. The YCV40 and YCS90. Beautiful. You should do a NAD thread.

I would also ask in the Only Traynor thread which is currently on page 1.
