Post Subject: I do not want to lose the “too idle” mode on 6C33CPosted by Romy the Cat on: 11/1/2010

 Paul, what are you talking about? I use from my 6C33C no more then 1-2W. The 6C33C at LF might give 20 W but it is load over to 600R. I load it to near 2500R (11.83:1 transformer with 15R driver) – you figure out your how much power and gain I burn in the transformer. I do not want to have more line gain; in fact I would like to have less line gain but instead to add some gain via transformer. It is sad that I do not have tabs on it.  What I do not know is why adding current help to get rid of clipping if the tube runs at voltage deficiency. Anyhow, I need to find a good balance between the losses in transformer and attenuation in my line level.  I do not want to lose the idle mode of my 6C33C operation as it sound very good for bass. I might go for 1500R loading but with fast core:

but there are some other consideration that I have in my mind. I do feel that I a bit idle the 633C too aggressively but it might be why my hyperbolic horn does not sound “hyperbolic bass” but rather as “tratrix bass”. You never know where you will find and where you will be lose….
