Yes you can, in power supplies, ARC for example is using 6550 in some of their Ref line. So why not a KT150.
KT150s in a Preamp Design?
I'm a bit of a shade tree tube amp mechanic; I'm no expert and have a decent but not comprehensive knowledge of design. Can someone tell me what's going on with this tube preamplifier design? I've never seen KT150s in a preamplifier!
