Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Try a 4P1L driver

I started off with 26s. Lovely tube, that was the inspiration for me to switch to only ever using DHTs many years ago. I used 3 stages because the finals - 2a3 or 300b - didn't have enough gain for 2 stages. Then I started to fool around with 4P1Ls. At some point I realised that if you used a couple of them in PSE you could get away with 2 stages - 4P1L into 4P1L. This tube has a mu of 10, and a low Ra which makes many things possible. Plus it sounds great.

I went back to using 26 for inputs as an experiment, but stayed with the 4P1L because it had better treble and was just a bit cleaner all round. So that's what I'd recommend to you as a driver stage. It will give you a cleaner sound and nicer treble. Plus they're still fairly cheap - I bought a couple of hundred years ago when they were peanuts.
