If I swap the stock JJ Electronics 12AU7 in my brand-new RSA Raptor for a Mullard, what changes should I expect in the sonic signature?

It's either a screaming bargain or an acceptably small loss. Also on my shopping list, based on what I've read here and elsewhere: Telefunken, RCA cleartop, Mullard, and "Bugle-Boy" made by Philips in the 1950s. Tube amp = hole in your desktop into which you constantly pour money. |
