So I got the new Traynor YBA200 all-tube head and I'm incredibly disappointed. This was supposed to take the place of my ailing (and heavy) vintage SVT but even though it uses the same power tubes and similar pre amp stuff, it sounds nothing like it. It's horribly lacking in any kind of mid punch at all. I play it with bass and treble at 0 and mid at 10 and it still can't cut through anything like the SVT. My next option is to get an Ampeg SVP-CL preamp and plug it into the power section of the YBA200. My question is will the toroidal transformers and whatever else Traynor used in this amp make much difference to the sound if I'm only using the power amp section? Eventually I may buy a dedicated power amp but as the YBA200 is fairly light it should do in the meantime and it does have 4 6550 tubes in it so it can't be all bad right?
