What's the greatest bargain in SET these days?

Charles, I'm fairly certain Brent Jesse has the Mullard CV378. A couple of other thoughts I didn't mention in my comments: The stage was enormous, all instruments were easy to identify, truly coming from black backgrounds. Voices were centered and extremely real. Nothing was syrupy. Totally organic and natural, the music flows as it should. Dynamics are fabulous. This little Dynamo can play anything, large orchestra, Chamber, Jazz, Rock, Folk; it gets it all right. This amp is going to be a lot of fun, not only rolling tubes and tweaking, but discovering the music all over again. And I have a great urge to go out and purchase more music because at heart I am a music lover and this little baby delivers the music.

Charles, I have had good experiences dealing with brent Jesse. I did not see CV378s on his list the last time I looked, but it is worth giving him a call anyway.
Got some more listening in tonight. These CV387s are really opening up.

Mikirob, I also found the Mullard GZ34/5AR4 to be an outstanding rectifier for the dynamo. I've never really found that tube to be all people make it out to be, but in the dynamo, it really shines. I have to tell you, as much as you like the dynamo, you are going to loose your mind when you hear the franks.

Mikirob,
I can relate to your genuine enthusiasm regarding this amplifier and it seems you and I have very similar listening taste and priorities. At this point in my life I've been fortunate to have experienced quite a large variety of amplifiers. Transistors (high or moderate power, class A and class AB) many push pull tube designs, OTL and class D versions. Within each category there's a hierarchy, some clearly better than the others.

No topology has gotten it as right as a well executed high quality SET IMO, nothing. They have introduced me to a level of natural sound and musical realism unmatched by other amplifier alternatives. Obviously this preference is personal and each person has their own choice to make. I get the sense that the SET genre will emotionally reach your music loving soul more thoroughly than other topologies have done for you.

Bill,
If Brent Jesse doesn't have the Mullard CV 378 I'll look to the ebay vendors. I value your judgment, so I'm motivated to get this rectifier tube into the Frankenstein based on your very high level of satisfaction with them.
Charles,

Brownsfan, Charles,
After the new house is finished (late spring) the first purchase I'm going to make is the franks. Between now and then l'll be having fun with the Dynamo. The Mullard is superb as it stands, but I likely will try some other rectifiers. The NOS Phillips 5R4GYS I firmly believe will substitute/perform wonderfully in some other compatible amp. A bargain at $65 from Upscale. Has anyone used KCA tubes? They seem to have a good supply of NOS RFT Siemens. According to Tim Smith, in his system the Siemens provided a "fatter, warmer sound". My only concern now is, how am I going to get any work done? I keep spacing out on the music.
