So, if I'm liking the matchless sound, I'd probably be happiest with a DC-30 clone since it has a similar preamp.

Kitarist suggested I knock around some of my questions over here, so here it goes. 

Some time ago I fell in love with the Matchless Clubman 35.  I am not a pro musician, so I cannot justify the $2000+ it would cost me to obtain this beast.  The Clubman has a pentode preamp much like the EF86 channel of the DC-30, but has 2 EL-34's in the Output stage.  So, I have the following questions.

If you are familiar with the Clubman, in what ways does it differ from other EL-34 amps such as the JTM50 or the TW Expression?

Do EL34 amps in general sound a lot alike?  Would there a be a huge difference in the clubman and the JTM50 for example when the only obvious difference is the preamp tube.

What does a rectifier do, and do I need it?

Would it be feasable to modify one of the existing ceriatone kits to make a clubanish amp? (i.e. Convert the DC-30 to an EL34 Output stage or change the preamp on the JTM50 to a pentode.)

Or...is the major difference between the JTM50 type and the clubman a Class A vs. Class AB thing?  I'm not sure how that affects the sound.

I also really like the sound of the Overtone Special.  That is a 6L6 amp.  I've seen things that suggest that it's easy to change EL34 amps to 6L6.  Is this true?

Yes!!!  A Clubman is all I ask.
